Are you wondering whether World of Starcraft is in development? WELL IT AINT.

During a StarCraft Lore panel at BlizzCon 2007, Blizzard's Chief Creative Officer Chris Metzen confirmed that the company, at least as of right now, is not developing World of StarCraft. He said the idea of creating an MMO based on their popular RTS franchise has certainly been discussed at Blizzard, but no steps have actually been taken to create the game.
 

Could Blizzard be very close to announcing Starcraft 2? Maybe... but in any event some sort of announcement is coming.

TeamLiquid has apparently translated a post from a Korean website which claims that "according to the game developers," Blizzard will announce Starcraft 2 at Blizzard's World Wide Invitational (WWI) to be held in South Korea. If you've paid any attention to Korea and Starcraft you'll know it's no joke over there. Our "hardcore" gets air quotes compared to Korea's hardcore, which should actually have just been written in all caps, bolded and italicized. Although we have absolutely no idea about the legitimacy of this Starcraft 2 information, we do know that there is a megaton announcement planned around May 19.
