Blizzard has announced their intention to follow up this year's Burning Crusade expansion with a new World of Warcraft add-on every year. While not terribly surprising, they have also announced that they're working on a major announcement for next year. Consensus seems to be that it will likely be another Starcraft game, given comments by Blizzard COO Paul Sams. "StarCraft is my absolutely favorite game of all time. As you probably already know, there is no doubt that we will continue the StarCraft and Diablo franchise, and trust me, I will be the happiest person in the world when we announce StarCraft 2."
