I just don't get it? If including kinect with every system means lower specs, inferior ports (from a technical level) and an extra $100 on the price tag, then why aren't they trying to leverage the damned thing at all? IMO lower game specs suck, but they might be mitigated by you know, actually using the kinect to enhance games somehow!
I'm not Microsoft R&D but I can image at least a few really cool things that can be added to enhance games using kinect. Aside from the voice stuff (which can be a cool plus) they could incorporate features like pseudo virtual window head tracking, bio-metric and facial feedback systems, environment/object scanning, etc. We want to see stuff that makes us say "who cares about a little resolution, my game does this, this, and this and yours doesn't"
This is the real problem Microsoft faces. Screw resolution; where is the kinect proof of concept that sells us on the 100 price tag?
IMO Microsoft have done, and continue to do, a really piss poor job developing and promoting any true gaming enhancing features for this 'essential' device they built their gaming system around!
Plain and simple; they either have to sell us on kinect or ditch the thing!
