I think they will be about the same. The only difference would be the controls obviously but also the fact that the Wii MIGHT support 480p and even then the Cube version will most likely be progressive as well....I doubt you will see any differences except for the controls...I myself MIGHT be purchasing a Wii and if I do I will be picking up the cube version....The controls look horrendous and I dont even want to give them a try...Looks to complex for the type of game and the Bow action really turned me off.
