Starcraft 2 video ?!

Update @ 21/05/2007: Blizzard 正式公佈 Starcraft 2

I don’t know if this video is fake or real, but it’s exciting!
It seems that Missile Turret can attack ground unit?
Also, there seems to have some kind of regional defense magic for Tank.

Anyway, I love playing defensing map and mission map, hope there are more customization flexibility for mappers to create more innovative map!
