Microsoft working on motion sensing camera?

Maybe you guys know about this already, but this is first time I've heard of it. It's definitely got me intrigued:

If this is true, it sounds pretty darn cool. However, it raises a couple thoughts/questions:

1) If this is indeed true, it would seem Microsoft may have Nintendo beat at their own game. However, I wonder how affordable it will be?

2) The article implies this is being developed for the 360. Even if this technology debuted only a year from now, wouldn't that be kinda late into the 360 lifespan to introduce something like this?

Then again, perhaps this technology will also be compatible with the next Xbox, at which time it will be much more affordable...

Can't say I didn't see something like this coming, what with the success of the Wii.
