I’m have no clue how Niesen determines this, but it seems that last generation systems are still being played more then this generations.  That a little surprising to me, for the x-box, because the 360 has been out for 2 years now.  Also if I payed 500 dollars for a PS3, I would be getting as much use out of it as I could.
