GDC Online suggesting an early 2012 release window for sequel-spansion StarCraft 2: Heart of the Swarm. GameSpot caught the quote during a panel, in which Canessa responded to future Battle.net upgrades by saying they are "a main area of focus we're going to be seeing on the Starcraft side over the next 18 months between now and Heart of the Swarm." However, a Blizzard representative told Joystiq "We have not announced a release date or window for Heart of the Swarm."
Blizzard's next release will be for the World of Warcraft (population 12 million) expansion Cataclysm on December 7. With that bit of news out there, hopefully BlizzCon's big reveal will end the hellish wait for a Diablo 3 release date.
