Activision has confirmed that this unveiling will be for a "fourth" Call of Duty game.

On the Web site of Call of Duty 2 developer Infinity Ward, an admin writes that some big news is coming out of the Encino, California-based studio this Saturday. After listing three famous events that have taken place on April 28, community liaison "fourzerotwo" says, "What goes down this April 28th is equal to, if not surpasses, the magnitude of any of those."
