Call of Duty: World at War isn’t out yet, but Activision is already making plans for the sequel on the fifth CoD game. The sixth part in the Call of Duty gameseries will be developed by Infinity Ward. It’s not sure if they will use the Call of Duty 4 engine for their new Call of Duty game. The setting of Call of Duty 6 hasn’t been announced yet either.
