Rumor: Infinity Ward giving Call of Duty 6 a sci-fi setting

Following the tremendous success of Infinity Ward's well-received Call of Duty 4: Modern Warfare, fans were generally disappointed to learn that the next installment in the wartime franchise would not only have a different developer, but would also be replacing their M4s with M1s, taking the series back to its World War II roots. If a recently uncovered rumor is credible, we're not entirely sure these same fans would approve of Infinity Ward's plans to throw the bullet-riddled franchise into the DeLorean, gun it to 88, and take it to where they don't need roads.

This rumor (and accompanying clumsy "Back to the Future" reference) finds its origins in a statement from an Infinity Ward insider, who mentioned the company is working on "a sci-fi title", and that further details concerning said title may or may not be made available during E3. It's extremely possible that Infinity Ward would get their hands back on the Call of Duty franchise once Treyarch has had its way with it, but would they really introduce elements of unrealism into such a history-steeped series, or could they be working on an entirely new, space marine-flavored franchise?
