I'm glad it's Startcraft 2, and not World of Starcraft. I was worried about having to choose between WoW, or WAR (if I switch when it comes out), and some new Blizzard MMO.
You know what I hate about RTS games? I suck at them. I actually LIKE the way they play, but I completely and totally suck ass at them. Anyone who was around when Warcraft III came out should remember our games we played. I pretty much always came in dead last, and was the first person to be out of the game. Most people don't seem to like playing against the computer in War 2, war 3, and SC, because it's just too easy and predictable. I don't enjoy it because the computer kicks my ass.
I remember in high school I used to play Warcraft 2 with a friend all night, every night. After a while we ended up doign us vs like 2 computer opponents. We tried me + a computer allied against just my friend, and I still got raped.
As horrible as I am at RTS, SC2 looks good. I'll probably do like I did with Warcraft 3: buy it, get through 5 mission in single player, get raped 2-3 times on battle.net, then shelf it.
