I'm really looking forward to SC: Ghost. I've always been a big gamer both on PC and console, so I have no qualms with switching systems.
I've always been an avid SC fan (my friends and I still play it on b.net all the time, even though it's years old) and I can't way to be in the SC universe on a first person level. The screenshots I've seen of the game are absolutely amazing to me. I never pictured ultralisks being so big, but now I understand why two groups of them can rip through pretty much anything.
Starcraft II needs to come out. Now. I agree Blizzard makes the best games around, and being such a big SC fan I'd love to see a sequel to it. Another race maybe, new units, new graphics, etc etc. I can't wait.
