OK, just finished the demo on Wii U. Overall, it felt like an inferior experience. The graphics are about the same on the 3DS and Wii U versions, but I found the control scheme (and control responsiveness) lacking on Wii U. Aiming was a big problem for me.
I love the Miiverse functionality planned for the game, but I can't justify another purchase. Haven't tried it on Xbox or PS3, but right now the 3DS version seems like the better option.
