CVG, the next Call of Duty game from Treyarch will be set in Vietnam and arrive at retailers this November. "It's going to be November again - just as with World At War and Modern Warfare 2," the source was quoted as saying.
We heard as much back in May of last year, when Treyarch was said to be looking for "Vietnam War era tunes." Add to that the fact that Activision's Noah Heller explicitly said Treyarch would no longer be working on WWII-based Call of Duty games and you've got yourself a more reasonable sounding rumor. We've asked Activision for comment and will keep you updated as we hear more.
