The issue for me is that 343 are using CEA as a testing ground of sorts. How to handle visuals in a Halo game, running the playlists on MM, setting up challenges and even adding features to support Kinect. In this time they will be analysing copious amounts of data in order to determine what they should and shouldn't do.
I would much prefer a mini-game that utilised Kinect so at least that way other players could simply accept the fact that they have no means of playing that mini-game. Instead, what is going to happen, is some players will get annoyed that a feature, albeit small and insignificant, is restricted behind a wall of silly marketing ploys.
Some non-Kinect supported Analyse feature that wouldn't have been as robust would have almost sufficed.
My point is; Restrict content for Kinect that actually requires the use of Kinect.
