Speaking during a conference call yesterday, Griffith said that the unnamed sequel, which many unofficially refer to as Call of Duty 5, will arrive on PC, PlayStation 3, PlayStation 2, Xbox 360, and Nintendo DS later this year.

The CEO did not elaborate further on the game's setting. His comments suggest that, contrary to past reports, the title may not return to the World War II setting featured in the first three Call of Duty titles.

As pointed out by Gamasutra, no details were provided as to which studio is developing the game. Job listings have indicated that Call of Duty 3 developer Treyarch may be returning to the franchise, with speculation that series creator and Call of Duty 4 developer Infinity Ward is already working on Call of Duty 6.
