And as for Kinect providing a unique experience, I'm no longer fully convinced on the basis of the initial line up. Project Natal from 2009 was a much more impressive product, understandable since the majority of the demos were simulated.
Dance Central and Kinect Your Shape were arguably the two most impressive titles showcased at E3, but Your Shape is already available for the Wii (comes with a camera that tracks the user's body for feedback) and with the exception of the flat, low res video outlines used in Kinect, offhand I don't see any fundamental differences between the two that make the Kinect version any different.
Dance Central was probably the most impressive title, yet I can't tell whether the 1:1 tracking of Kinect actually translates into 1:1 on screen movement or if it simply plays back canned animation either matching the ideal, or displaying "goofs" when the player makes mistakes. It does not appear to actually make the in game characters track user movements 1:1 or the user would be able to break into the Robot or start doing back or headspins during any song and make their avatar do the same, which I'm pretty sure isn't the case.
