Last year Sony surpassed MS in performance by sheer luck since MS has poured resources on Kinect 2 and TV. With MS's resources and software expertise along with huge R&D spent in general on various solutions, I honestly doubt Sony would manage to reach yet alone surpass MS's offrring. It is amazing how well rounded it is this time around, incorporating various state of the art technologies. The thing doesnt sound like a beast only in numbers. Its all these additional solutions that improve efficiency by a large margin that are expected to immensely heighten image quality and variety on screen. And I am sure we have yet to hear everything.
