Call of Duty 5 is an amazing game despite the fact that it is still set in the played out genre of WWII. The game exceeded despite this obvious redunduncy.  Now, CoD 4: MW2 is still six months away, we hope, and will be developed by Infnity Ward. Treyarch has earned the right to dev CoD 7 people say and have maybe tipped their hand to what era the game will be in:

A source we consider reliable has told TVGB that Activision is looking to licence music for “Call of Duty 7,” music that gives some serious hints as to the locations the game may take us. Mentioned were Vietnam War era tunes, as well as Cuban, African, and Soviet Union music. The source says Call of Duty: World at War’s senior producer Noah Heller is involved, so it looks like Treyarch is once again developing.

I would love a Vietnam era game. The weapons are still decent, M-16, M-60, M-79 and obviously the AK-47. No one really has much to say about the Korean War and it is too soon to do Gulf War, ask Konami. We will keep you updated.
