Presumably, those two titles would be Heart of the Swarm (the Zerg-based expansion for Starcraft 2) and the long-awaited Diablo 3. Blizzard president Mike Morhaime joined the call after Tippl spoke and promised that more information was coming about both. Blizzard's developers, he said, are hard at work on Heart of the Swarm, and we'll hear more "in the coming months."
Additionally, Morhaime said that he would talk about Diablo 3 "and the upcoming beta on the next call," in about three months. "Until we get to beta and have the community help us test the game," he later said, "we're not going to lock in a release date."
Blizzard is also working to get both World of Warcraft: Cataclysm and Starcraft 2 out in China, but had "no specific updates to share at this time" about those releases -- or the "Titan" MMO, for that matter. Morhaime did plug both the upcoming BlizzCon and Blizzard's twentieth anniversary this year, and closed by saying that "the games we have in the pipeline represent the best and widest slate of games we have ever produced."
