IGN's UK division chatted with Infinity Ward's community manager Robert Bowling who states, "Right now we don't have a clue what our next game is going to be, and we won't know what it will be until we finish with Modern Warfare 2, which won't be for a while . . ." By "finish" he means not only releasing the full game but also getting feedback from fans and then creating the planned downloadable content releases.
