Blizzard will be making a "major product announcement" in 2007, according to an IGN interview with the developers COO.
Paul Sams told IGN that Blizzard was currently working on at least three other unannounced titles at the moment and, just to rub it in, dropped StarCraft's name.
"StarCraft is my absolutely favorite game of all time," Sams told us. "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."
I'm not sure which I want to see more: StarCraft 2 or Diable 3.
