God, people are foolish in General....
1. Warden has a 'hiccup' at times because of the way that Wine/Crossfire (Not bringing anything else like cedega into this- not familiar enough with it) API calls handle memory management. While it is incredibly similar, there are tiny differences that can may seem like a third party application is manipulating resources divested to Diablo 3- despite not doing so.
2. Yes, WoW used to have this issue some Eons ago. It no longer does. Been playing it in Wine for a while now (up until the moment I quite about 6 months ago anyhow) without any problems.
3. Surprisingly, a good lot of companies is beginning to develop or has already developed games for Linux. EA, Valve, Origin, S2Games, iD (Well, not so much develop native clients but the code-base remains the same and they toss out a Linux binary to launch, say, Quake 4, Doom 3 or ET:QW natively. Quake live has a native linux browser plugin for a while now). This is a small list, but I don't care to look up others at the moment.
The amount of code it would take Blizzard to change warden to tell whether Wine was in use? About a day's work at most- while swamped with other projects. No more than 100 lines, imho.
This is not simply a matter of 'LOLOL DERP DAT OS NAWT SUPPORTED HEE HEE I NO HOW CLICK BUTTANZ!111111', but an issue of willingness to support alternative platforms. From a corporate and customer-oriented standpoint, they would have to add further overhead (Staffing for documentation, technical support, community, etc etc) to support yet another platform.
For that matter, if you're familiar with some of the remarks that folks at Blizzard have said, it is that they are quite Linux friendly. However, continuing from my previous point: On the business tier they likely don't find the appeal in putting out a solid Linux client for their games since Linux still wavers at roughly 1~5% share (making it a distant third from the gorilla of the marketplace, but not tremendously far behind OS X, which has been fluctuating at an average 8~10%).
This last point is now a factor triply so, methinks, as Activizzard has mostly succumbed to greed.
Right, forgot to mention one thing: Someone pointed out that Linux is not really plug and play with most hardware. Hogwash. Been using it as my main OS for some years now and its fine 99% of the time. The only time I've ever had an issue was with a wireless card on my buddy's laptop- but that's because the company has gone defunct and the driver needs to be downloaded for it.
