On the newly-created www.activisionblizzard.com website, various high-profile sequels are now being touted as officially in development. Under the Activision branch of the merger, Guitar Hero IV and Call of Duty 5 are among the higher-profile games mentioned, with others such as new James Bond and Tony Hawk games as well as new DreamWorks projects and a brand-new Bizarre Creations racing game.

Franchises mentioned in the same fact sheet on the Vivendi Games side include Blizzard's World of Warcraft, Warcraft, StarCraft and Diablo series along with the likes of industry staples such as Crash Bandicoot and Spyro.

Who will be developing Call of Duty 4's sequel?

It's worth noting that the developer tackling Call of Duty 5 has not been revealed at this time, but given the runaway success of Infinity Ward's recent Call of Duty 4, it would seem that this developer would be the natural choice. We'll be bringing you more information on these upcoming games as it becomes available.
