I don't get why people are so quick to defend a company's best interest. Some of you guys sound as if kinect fails you will lose your jobs / wife / cars / insert important thing in one's life here.
It is Microsoft's job to sell me on the kinect and so far it's just an interesting but deeply flawed tech demo. They have their work cut out for them to really improve on this or just let it go (I personally wish they'd focus their attention elsewhere but alas, microsoft appears to be set on this path).
It's most definitely not becoming a standard across all games just because it's packed in with the Xbone, Ps4 doesn't have a kinect or direct alternative out of the box, so the majority of games will probably not have any motion functionality (unless the Xbone dominate the market, which seems very unlikely at this point).
I think this will be like the Vita back touch in the long term, it's there and first party devs will be forced to use it, but hardly anyone will come up with a worthwhile concept for it.
