Ubisoft has already done various themed (experience) dance games , using the JD template they began with Michael Jackson and it's trying its luck this year with ABBA and the Black Eyed Peas. I don't know if you've seen the trailer of this game, but it seemed to deveate from the filtered videos to 3D models.
Notice anything odd in this next one?
That's right, the Wii can't handle 3D models. This omision of footage seems to have worked as seen in an amazon review. There are many maniac dancers out there who will still buy it just for the band or songs, but will the Kinect version of this experience outsell the Wii this time around?
