Are you sure it's "undiluted" as claimed? On of the cornerstone of COD being a good game is its rock steady frame rate. From numerous reviews around the net, because of the dev wanting to get as close a COD4 look, the game may look beautiful but framerate suffers. Compound that with the control mechanism being a motion controller that REQUIRES precise and stutter-free framerate to be able to control onscreen cursor, I'd surmise that you will be battling the game controls than any in-game terrorists when the framerate start dipping wildly.
