It looks great, but you know how Nintendo is; they can imply a ton from a trailer, only to mislead us in the end. From the video, it almost seems like there will be a training aspect, with a story and the whole sha-bang. If so, that will be great. If not -- disappointment for me.
I'm also going to be pissed off if they don't make motion the focus of control. I'm tired of Nintendo hedging on that. It's bad enough they're giving us motion control as it was supposed to be pretty much 3-years after the fact, but to cling to the old ways is a disservice to those of us who bought the Wii for what only it could do.
