I also don't see how much of a difference it makes that it's a port. It's still the same game, except that you can't see your super important HD reflection in the water, etc.
Rate the game, not the platform.
I dunno how they're going to fit the ability to drop weapons, toggle fire modes, toggle night vision, lean, use binoculars, open the nanosuit menu, and open the map; all while including the core movement and combat controls; on a freaking Xbox controller.
