Call of Duty: Black Ops 2 was recently leaked for preorder on Amazon's French website and was later removed. While this isn't confirmation of anything, it certainly does strengthen the possibilities of the next Call of Duty game being a sequel to Black Ops.

While it is possible that Black Ops 2 is a placeholder name, not much can be gathered from this other than that Treyarch are indeed releasing the next game and that the game should be about the same price as usual.
