IGN writes: "No word on whether Infinity Ward, the developer of Call of Duty 1, 2, and 4 will develop the game. Up until recently the next Call of Duty was speculated to be developed by Treyarch, the developer responsible for Call of Duty 3, and was rumored to once again take place during WW II. The rumor surfaced when Treyarch looked for a new company position:
"Working experience with First-Person Shooter or Third-Person Shooter genres (console or PC). And if you're a fan of World War 2 shooters, then even better!"
The December job posting has since been taken down. IGN has contacted Activision for clarification, but so far no representative was available for comment. More on the story as it develops."
