While Activision Blizzard's annual report, released last Monday, revealed news about this week's Infinity Ward shake up that's not all that can be found in an otherwise dry report. It states that the Blizzard side of the operation is working on, among other things, "sequels to the Diablo franchise."

Yes that does suggest that Blizzard is working on more than one game in their action-RPG franchise. At the moment, the developer has only admitted to working on Diablo 3, a game that won't be out until sometime in 2011 at the earliest. It's possible that the Activision Blizzard report means that expansion packs to Diablo 3 are in the works, much like two more StarCraft II games will be released the one that's coming out later in 2010.
