I'd be interested in knowing more about how they intend to standardize motion tracking quality.
As for the rest, I don't really care except for geometry, color, & greyscale accuracy. In augmented reality, it does actually matter how CG objects look relative to their surroundings. A poor quality, uncalibrated display can surely affect the experience (and much worse than simply watching a movie on a non-THX certified screen, IMO).
It's not that I don't care about smooth video playback, but they're only talking about playback of video files/streams - not about AR apps.
