The superior control scheme might result in some neat gameplay mechanics, and knowing that graphics are already good, I'm happy with it.
Now the HD versions might have a kind of generic game, especially the X360 because it has Left4Dead 2 and Natal doesn't work at all with FPS's.
For PS3 they can use the Arc, but holding the dualshock 3 and arc on both hands will just kill any good gameplay experience.
That's why I believe the Wii version will rock.
