If all the footage from the video was from the wii-u version I might actually get a wii-u, that looks way better than anything for the wii. I was fairly impressed with the number of enemies on screen in a couple of those shots.The ending was just silly, but I would expect silly gimmicks from Nintendo.
I noticed the fancy controller looks like it's plugged in to the console, I hope it's wireless too. I'll pass for sure if it's not wireless, or at least has a really long cord to plug in. I hate having to move my couch closer to the TV to play some games like guitar hero because the cords aren't long enough.
