lol, first of we dont have any statements from other people than the one who posted that post, how do we know if he is kidding or not?
Second, it wont be SC2 because blizzard has all the registered rights for any game in the starcraft series. "StarCraft" is a registered trademark and if anyone makes a game called StarCraft 2 without the approval of blizzard, well then blizzard has the right to sue their asses for millions of dollars.
Besides from that, anyone who choses this forum for posting the first official news about the game in stead of broodwar.com probarbly haven't even played starcraft more than 2 weeks, and the game would suck.
