Call of Duty: Black Ops and Ghosts just aren't enough anymore. While Treyarch and Infinity Ward have been doing a great job of passing the Call of Duty torch back and forth every year, Activision seems to want more. They plan to accomplish this by adding a new developer into the rotation and announced in their quarterly financial report that Sledgehammer Games will be developing this year's Call of Duty title.
By adding Sledgehammer, both Infinity Ward and Treyarch will have a longer development cycle for their next Call of Duty games. Activision mentions Modern Warfare, Ghosts, and Black Ops in its report as the three branches of the best-selling Call of Duty franchise. Treyarch handles Black Ops and Infinity Ward handles Ghosts, so Sledgehammer's first entry as a standalone developer for the franchise will likely be a new Modern Warfare title. They previously worked with Infinity Ward in developing Modern Warfare 3.
The good news for gamers is that additional time between each company's Call of Duty game should lead to a better product. The bad news is Activision doesn't want to give the poor cash cow a break.
