According to This is Game, Blizzard will announce the sequel to StarCraft at the World Wide Invitational, to be held in South Korea on May 19th. Here's a translation of the post:
I couldn't believe how addictive StarCraft was when I first tried it...that game should come with some kind of surgeon general's warning. The question is, assuming the rumor is true, of course, would this drag players away from Blizzard's golden child, World of Warcraft?
