Third Call of Duty team formed?

Infinity Ward, Treyarch and... ?

Just when we were getting used the yearly swapping of Call of Duty development between Infinity Ward and Treyarch, Activision's gone and signed a third developer to work on the mammoth shooter series, according to reports.

The LA Times writes: "As Activision seems to be discovering this year with Guitar Hero, there's danger when a title is overexposed with too many iterations. Nonetheless, the publisher has aggressive expansion plans for Call of Duty.

"Although Infinity Ward and Treyarch have produced sequels in alternating years since 2005, the publisher now has a third development studio working on future versions," it writes

The mysterious third studio isn't named in the article, but Raven, High Moon and newly-formed Sledgehammer are all likely candidates if the report rings true.

A third Call of Duty in the cycle could potentially give Infinity Ward and Treyarch more time to work on the core series than the traditional two years, or more likely the extra team is working on the previously mentioned CoD MMO or subscription service.

The way Infinity Ward's calling the shots at the moment, we wouldn't be surprised if it's decided to work on something else entirely, and now Activision's simply covering the Modern Warfare gap. We'll let you know when we hear more.
