I know this will likely add fuel to the Zombie hype fire, but it occurred to me earlier. Remember there was all that hype about Area 51? And then some extremely intelligent person (Well done mate ) snuffed that out by saying that Area 51 did not exist during WW2. Im fairly sure, however, that it did exist during The Cold War, the setting of Black Ops. Treyarch did say they would return after all.
