somewhere i'm sure they'll have the head tracking patented - when they first saw the Head Tracking project do you honestly think Nintendo's reaction was:
1: Wow thats amazing - lets look into that and see if it's plausible
or
2: Bstartds!! now he's blown it - cant believe somebody else his figured it also.
There's probably dozens of components laying dorment in the Wiimote for a dozen different purposes put there purposly just waiting to spring into action when called upon.
At the same time however there's probably a million patents that they registered that will never get used. I'm sure these web jounalist experts will keep guessing but to no avail.
