Activision Blizzard is nothing if not forward thinking. While Modern Warfare 2 is still months away from release, rumors are already swirling about the next Call of Duty game after that, which would be the seventh in the series. According to a "a source we consider reliable," That VideoGame Blog reports (via Destructoid) that Activision has been seeking to license Vietnam War-era music, as well as Cuban, African, and Soviet Union music -- indicating the game could likely be set between the 60's-80's, taking place in any of the aforementioned settings.

Also passed on by this source is that World at War senior producer Noah Heller will be involved with the game, which means Treyarch would once again be at the helm. That VideoGame Blog notes that Heller has previously stated that "we're happy that we put [World War II] to bed" in the last game, further indicating a change in setting for Treyarch's next installment.

While a Call of Duty title set in the Vietnam War would be an obvious guess, the breadth of scope of the music being licensed seems to suggest Activison may be planning a broader scale -- perhaps touching on a number of other proxy wars and conflicts that took place during the Cold War. The Bay of Pigs invasion? Cuban Missile Crisis? Afghan-Soviet War? The era sure seems to offer a lot of grist for Activision's mill.
