I'm feeling fairly ambivalent. I'd love it if it was introduced well, but TP was absolutely horrible at recognising your moments, shields and spins commonly being mistaken, and it had about half a second of lag compared to the input from a controller. I think the best option would be to allow support for multiple types of control, like Brawl and MKWii have had, but if the Motion Controls are much better done this time, I'm all for them.
