While Infinity Ward may be dropping the "Call of Duty" title for its upcoming present-day shooter Modern Warfare 2, you can bet that publisher Activision has more games in the Call of Duty series in the planning stages. A rumor over at ThatVideoGameBlog.com claims that a so-called reliable (but unnamed) source has told them Activision is looking to license music for "Call of Duty 7."

The story claims that Activision is looking to get their hands on "Vietnam War era tunes, as well as Cuban, African, and Soviet Union music" for the game. Treyarch is the likely developer of the next Call of Duty title (they have traded with Infinity Ward for every even-numbered year) which means you can look for this next historical FPS sometime in 2011.
