This is not too far from what I thought would be the final result, after reading an N-Sider editorial on IGN a few months back, though I envisaged the motion-sensing component being more the add-on rather than the central focus. Players on the Revolution aren't going to be as inactive as a lot of previous consoles have been blamed for being, in light of increasing obesity (quickly looks in the mirror). My only concern is that for people with mobility restrictions and disabilities (I have a muscle disorder which means I exhaust my ability to do strenuous/repetitive actions fairly quickly) are going to have some trouble with this, though it might be interesting to see how things go with a bit more regular exercise beyond what I force myself to do.
I think the custom controllers for this could be interesting, though. A lot of people have already mentioned playing the next-gen Zelda where you're swinging a sword, how about if the main motion controller was replaced with a Master Sword mini replica and the analogue stick add-on was built into a shield that was also motion sensitive. Not only would you be swinging your sword around, you'd be blocking with your shield too.
