One of the guys who got up and asked a question at BlizzCon managed to get his question jumbled and sort of half-answered, so we've followed up directly with him. But we know it's a big topic throughout the community, and so we decided to share a response Wyatt wrote up. This is pretty raw internal dialogue, so please be keep in mind that it's rather mathy, assumes you know a lot about internal mechanics of the game, and of course... nothing is set in stone.
For any Wizard (that doesn't use Golden runes and/or the passive that makes academic/signature skills add arcane power) the only regeneration you have is passive. Of two weapons with equal DPS, but one with a slower attack speed, you overall better damage for the skills that actually spend arcane power, while your academic/signature skills are no different in damage done for the same time spent.
Okay so first I'll start by saying that all of your math is correct, (except for the one exception case that I'll mention later). The conclusions are all based on information you have available, so mostly I'm going to mention a few things to consider, and then I'll fill in with additional information to complete the picture.
First, a few qualitative comments:
Yes, your build absolutely matters. Some builds may be well designed to favor 2-Handers, and some may favor 1-handers. So the general statement of "The correct weapon depends on your build" overrides everything else I write.
Additionally though, two general rules of Diablo weapon speeds still applies - spilled damage matters, and speed matters for combat effectiveness. In WoW, you might use a 1.5 second cast spell over a 2.5 second cast spell because you simply can't afford to stand still that extra 1 second. How many spells in WoW do you cast purely by virtue of them being instant cast or castable while moving? In Diablo, virtually every spell is working off of your weapon speed, and the need to be able to quickly move 1/10th of a second sooner sometimes matters. Spilled damage matters too. Many aspects of Diablo involve fighting hordes of small monsters. When a monster has only 150 health, who really cares that you hit it for 300 damage instead of 200 damage? Either way it's dead. And if it's dead with a faster weapon, that means you can get to the next monster faster. This means that a weapon with a 1.3 speed that can 1-shot enemies actually has a 30% killing throughput increase over a weapon with a 1.0 speed.
"But I don't care about these edge cases".
Well first, I would argue that in Diablo, these aren't edge cases, they are a core part of the gameplay that come up all of the time.
HOWEVER, for those who are insistent on maximizing theoretical DPS and AP usage, we've decided to cover you anyways.
First, straight up. all things being equal, 2-handers do more damage than 1-handers. This is pretty obvious, but I want to confirm and validate this. The reason it's important to call this out is that all the calculations assume "for any 2 items of the same DPS". But that's not a great starting point, because for any two comparable items at any given level, 2-handers do at least 15% more damage than 1-handers, and in many cases 20-25% more.
To put it another way, many of the posts in the linked thread make an assumption that two weapons are equal DPS. This assumption is flawed - what you really want to ask is "For the theoretically best 2-hander in the entire world (even though I'll never get one)" vs. "the theoretically best 1-hander in the entire world (even though I'll never get one)".
However, what you choose to put in your off-hand, should you choose to wield one, matters.
First, no matter WHAT you use, you are getting a bunch of extra stats. In addition to DPS from Attack and Precision, you're getting whatever other item stats are on your offhand. So you're trading off a theoretical Arcane power efficiency boost for the stats of an offhand.
Furthermore, if you use a shield, you're getting a big armor boost. If you haven't played Diablo in a while, people easily forget, but a lot of Sorceress players used a shield in Diablo II. For some players there is a "fantasy" of "I don't need a shield 'cause I don't plan on getting hit". The reality is that we don't let you get away with that in Diablo. You get hit. We don't have heal, tank and DPS roles in Diablo, so everybody in Diablo eventually takes damage.
Additionally, if you choose to use an orb, every wizard Orb (and witchdoctor Mojo) comes with +dmg on it. So if your mainhand does 8-10 damage at 1.4 speed, and your orb adds 3-4 damage, then that means you're doing 11-14 damage at 1.4 speed. In many cases the orb + the stats on the orb completely closes the 15-25% DPS gap between 2-handers and 1-handers.
Add on top of that +dmg from your rings and amulets, and currently with internal tuning numbers (this may not be how we ship), but 1-handers + offhand out-DPS 2-handers almost all of the time. It takes a luckily rolled 2-hander to out-DPS most 1-hand + offhand setups if you can also spare some +dmg on your rings and amulets.
Finally, fast weapons are better at fishing for procs. Diablo has lots of very cool proc effects. Chance to gain Arcane power on critical hit. Chance to summon a fetish on spell cast passive on the Witchdoctor. Faster and more frequent casts means more opportunities to fish for procs.
Where does that leave us? Well currently for internal testing of Inferno mode, 1H+Orb is overwhelmingly better. You get more damage, better mobility, more stats, and more proc fishing. 2H gets you better Arcane Power efficiency. If anything I'm currently worried that 2H is too weak. The most likely solution on this front will be to reduce the amount of +dmg found on rings and amulets to reel in the damage advantage of 1H+Orb. However, the value of Arcane Power efficiency varies the more you have to run and move. If you're running and moving constantly, then AP efficiency lets you drop big bombs like meteor and Hydra when you finally get to stand still. Since the amount of running and moving varies from situation to situation, I'm actually fairly happy with where things are.
On the topic of Disintegrate and Arcane Torrent, we're actually currently considering a change to make them drain AP faster, to match the drain rate on all other skills. I haven't decided yet whether it's better for the game for the philosophy on AP to remain consistent across all skills, or if it's cool that 2 skills break the rule. (Ray of Frost breaks it too BTW). I am currently leaning towards having it drain AP faster because although I absolutely LOVE having different skills for different builds, I also think that when it comes to your resource system, having some standardized themes is what makes it possible to design all the OTHER skills/systems that break those rules. For example, standardized "fast weapons drain AP faster" is also what let's us do "Arcane power on Crit" that let's you feel like you're cheating with all the skills.
On a side note, I don't think you actually get any potential DPS increase by being able to squeeze in an extra cast in between casts of meteor because the time of 4.8 seconds is the amount of time it takes to regenerate back the AP cost of Meteor, but it's not like any additional AP just 'disappeared", you still have it. A 65 AP cost spell gives you a 35 AP buffer to pool over multiple casts. So let's say that you figure out your theoretical breakpoint is "6.9 electrocutes in between every meteor" and you think you're going to get an extra cast if you can get that to "7 electrocutes between every meteor". That's not really correct because 6.9 actually plays out as "Meteor // 6 Electrocutes".... repeated 9 times followed by "Meteor-7 electrocutes".
To be even more pedantic, (but I know you theorycrafting folks geek out on this stuff anyways), this has never actually come up as a balancing issue in any of our internal tests because a Wizard never stands still shooting long enough for this to ever actually matter. The truth is that you're going to weave in other skills, or have to spend time moving, or whatever else long before anything in the previous paragraph matters.
Your name is Wyatt?
Exactly. And your Wyatt, so your name is Wyatt. Why no? You just validated what i said...
You reported Bashiok :O

No, he's saying that the person named Wyatt is named Wyatt, which isn't him. His post is quoting the guy named Wyatt who answered this question from the guy at Blizzcon.
Does that mean that the difference between a quick Wand and a slow one handed hammer (or something) is insignificant, or is it balanced due to the benefits of proc fishing vs taking out that one big scarey guy (unique or what have you) 1-2 'meteors' sooner on top of not having to stand for a full X.Y seconds casting? Or is this just not a problem (maybe the hammer being much worse for a caster) as melee casters are more balanced when using specials/daggers/swords?
BTW Thanks for the Great detail! Answered all my concerns except the above!
PS. Not the Blizzcon attendee
He's referring to the PPM mechanic, not the internal cooldown/high chance one. Procs per minute basically says that if your weapon has a 2PPM proc, a 3.0 speed weapon will have a 10% chance of proccing that proc, and a 1.5 speed weapon will have a 5% chance, so being a faster weapon doesn't give you on average more procs in a given amount of time.
