They're patenting the system. It was filed six months ago. It's not necessarily indicative of how far along in development of the game they are, nor is it necessarily connected to a game (though it seems pretty likely at this point).
It's basically a Nintendo-fied version of having multiple difficulty levels. Kind of like how WiiSpeak is their Nintendo-fied voice chat. ;>
