So at E3 they stated that the 3DS version and the WiiU version would have the same exact characters for various reasons. So its not crazy to assume that it will basically be the same game, levels and all.
Now my question is why the hell would the 3DS versions be cheaper? Just because of the smaller screen? It has 3d too!!
I should have just gotten a 3DS instead of a WiiU... it has all the good games
