I am pretty stoked for Starcraft 2, actually. I haven't owned a Blizzard game since Brood War (I just don't have a gaming-quality PC), but I feel that Starcraft had the best-written fiction of any of the Blizzard properties, and I am really excited to see what happens next. Of course, Blizzard has one of the best track records of any developer, so it's safe to say the gameplay will be outstanding. I may not be much of a PC gamer or a RTS player, but I will make exceptions to both for Starcraft 2.
However, I am going to be a heathen and say I am more excited for the upcoming Super Smash Brothers Brawl announcement. In fact, I think I am going to go dig up the thread.
