Heart of the Swarm Update - New Videos

A large number of StarCraft II: Heart of the Swarm demo stations were featured at the MLG Spring Championship that ran June 8-10, where attendees sat down to see the future of StarCraft II multiplayer first hand. We wanted to share the excitement with players who couldn’t be there in the flesh, so here’s a video featuring the latest updates to the Heart of the Swarm multiplayer units.
The video you’re about to watch includes all the latest updates we’ve made to the new Heart of the Swarm multiplayer units since they were unveiled at BlizzCon last year. Check it out to see the latest changes:
Now that you’ve had a chance to see what the new Heart of the Swarm units are all about, let’s watch them in action! Day[9] and Blizzard’s own Rob Simpson shoutcast these battle reports for your viewing pleasure. A big thanks to Day[9] for dropping by; you can catch his show on Day9.tv Sunday through Thursday at 7:00 pm PDT.
Zerg battle protoss in this battle report
Terran face off against zerg in this battle report.

(God why did you make people this stupid?)
If they don't add the new race or at least five or six new units per race in addition to the ones they've already announced then SC will be going the way of Diablo.... down the crapper.
here is my thoughts:
Zerg:
Ultralisks should require burrow to use new ability.
Vipers: i was curious if they can sap hp from buildings being constructed (my concern is that a drone will keep canceling a cheap extractor on the move to power them up.
Toss:
the new capital ship (tempest) need something in addition , like an upgrade to make it more exciting. it doesn't even have to be an upgrade to do more damage, it could be like detection. although my vote for is to let them carry interceptors
Terran seems ok for now, but i don't know how they match up against toss yet. I want to know what warhounds and battle helions are weak against.
