According to Kotaku, one of their sources close to the developer has revealed that Wolfenstein and Singularity developer Raven Software is working on an upcoming Call of Duty title.
Apparently, the studio has been pulled off its own current projects to help pick up the slack on an unspecified Call of Duty game.
Other rumours floating around the internet suggest that Raven will be working specifically on a series of map packs for Call of Duty: Black Ops, which is currently being developed by Treyarch.
Infinity Ward (or what remains of it) is supposedly busy working on new maps for Modern Warfare 2.
