Cod4forums.com "Call of Duty 6, with the recent information acquired we believe this game is already started in development with Infinity Ward. Treyarch worked on the prior game (Call of Duty 3). Given that setup, it is plausible that Treyarch would now be working on Call of Duty 5 while Infinity Ward moves onto Call of Duty 6."
