That VideoGame Blog reports a rumor suggesting the Vietnam War and/or other Cold War conflicts may be the subject of the next Call of Duty Game, a theory also supported by comments by Activision's Noah Heller last year referring to World War II saying, "we're happy that we put the war to bed." The rumor is a little sketchy, however, as it is based on their understanding that Activision is looking to license music for the seventh Call of Duty game that includes "Vietnam War era tunes, as well as Cuban, African, and Soviet Union music." They attribute this tidbit to a "source we consider reliable."
