Well while I completely agree that kinect did not deliver the experience that was being marketed by Microsoft. Marketing it like they did was actualy great, they sold a hell lot of units and selling a hell lot of units is the only reliable way to get dev interested in the device. Unfortunatly and understandably the device never got past the 'gimmick' state as it received mainly shovelware and integration that were only meant to use the word 'kinect' for pr spin.
The real issue with kinect was Mattrick
Before Mattrick, Xbox was literaly on fire (not only because of RROD XD), the lineup was full of new ips, Microsoft was trying hard to get into Japan (and yes they achieved some results), and Xbox live was way ahead of the competition.
When Mattrick took over he literaly put an end to all those to focus on Kinect. Very few new ips, end of 'Japanese push', Xbox Live was caught by competition.
The only reason he was allowed to do this was because he was IMO wrongly (or at least way too much) credited for bringing the Xbox 360 from 25m units to 80m units and Mattrick himself credited to much Kinect for this success which also led to the crappy reveal of the Xbox One.
But in the end I did enjoy some title like the first kinect sports.
