Forum:Whats next for Call of Duty?

What's next for Call of Duty?
We all know that there's gonna be an MW3 and there's a possibility for Black Ops 2, but then what? It looks like the only place COD has to go to stay fresh is to the future. I don't see them doing WWII for obvious reasons and any war before that would be too low-tech for COD (sleight of hand might as well be the only perk if every gun is gonna take 15min to reload). Also the Afghanistan and Iraqi wars would be, in my opinion, too similar to Modern Warfare. So I'm asking you guys and girls what next? PS: Sorry for the errors I'm new to wikia
