TOTAL geek squee.
Starcraft 2 is official. And it’s not a huge variation from the original game – updated after, what, 8 years, naturally, but same 3 races, new vehicles and ships, new engines, all that, but it’s the same game, redone.
Starcraft was one of the few games that totally sucked me in, and I still occasionally play it, years and years later.
The Wikipedia article on Starcraft II is under heavy editing right now, but the details are there.
I highly recommend watching the full cinematic trailer. It totally rocks.
