Ok I found this out. First of all, we all know the cord that hooks into the Wiimote for the Nunchuk got smaller (they should make it like an ipod but oh well) Now if youve watched the sensor bar. It changes as well. It has had 3 stages. I believe this is thier order. The Small circle one, big one, then mid size rectangle
sinec i couldnt find links, if you watch the teaser trailer here: http://media.wii.ign.com/media/821/821973/vids_1.html you will see it, and this is a pretty new movie so thats why i think its the newest
Okay, sorry you can close, or just discuss the 1 change. I guess when you see the wiimote in action its hard to tell how big the sensor was, it looked smaller honestly!
