2 million may be stretching it. It all depends on how well Activition and retailers support the game, if its on store shelves it will continue to sell for a very long time.
I think 1 million could very well be possible (with over 500K in the holiday season alone), but im not too sure about 2 million. None of the insanely popular COD games on Wii have sold 2 million.
