I expect Kinect 2.0 to sell very poorly once it's available separately, unless it's priced very low, so about $60 or lower. Anything higher will not work.
Also, I expect a flood of used Kinects on the market, which will additionally undercut sales of a newly packaged machine.
The only way for any answer other than the first one to happen is if MS publishes some truly magnificent Kinect AAA games (Halo, Gears Kibect only titles) that work impeccably well and flawlessly.
Other than those improbable outcomes, Phil Spencer just took it out behind the barn and shot it, while telling everybody it's at the uncle's farm upstate.
