In an interview with CVG, Treyarch senior producer Noah Heller didn't rule out more World War II for future Call of Duty games. He said there are still a lot of battles left that could be turned into a Call of Duty game:
"I can't say that there won't ever be a WWII Call of Duty game again, but we're glad we were able to end the war and we're glad we're going to support the title with lots of downloadable content," Heller said.
"It's gratifying that we're able to show the close for once, rather than the opening," he added. "The war is over and both campaigns have a very clear ending."
"But in the meantime people definitely haven't seen the final charge of the Red Army, people haven't seen what the fighting was like in Okinawa and I think it's definitely important to show those stories from a polished perspective rather than show some of the mopping up elsewhere in the world."
