Activision is not only working on a Call of Duty sequel for the PC, but also on a sequel to last years Call of Duty: Finest Hour. Call of Duty 2: The Big Red One will be set during World War 2, has a tentative holiday season release date. Previously Activision mentioned it would be showing "two" new Call of Duty products, so besides the CoD2 for PC, this may be the second one.
