That's a little rumour Giant Bomb are putting out there. Apparently Activision, as part of their pledge to innovate with the next instalments of the long-running franchise, have taken the series creators (and sole developers for the last decade) off the property, and have handed the reins over to Robomodo, a new studio consisting of former EA Chicago staffers. A studio who are currently "working on a project for Activision".
