Eh, that'd be Move he'd be angry at, Kinect is more an evolution of motion controls than a wii clone.
Right. Kinect, while being a direct competitor to the Wii, is definitely different than the Wii on just about every level. The only real similarity is that you use motion to control games and it looks like there will be a ton of shovelware just like the Wii.
Oh, and Miyamoto is just a game dev, i don't think the Wii was his idea anyway.
