Blizzard has a few titles in development that are public knowledge, such as a World of Warcraft expansion, Diablo III, StarCraft II, and another next-gen MMO, but it is also looking to fill two job openings, revealing there might be yet another title in the works: "Blizzard Entertainment is seeking an experienced gameplay engineer to focus on game rules systems for an unannounced title. This is your chance to get in on the ground floor of a dynamic and focused team working on a brand new project."
