I sure hope this wasn't the only thing they wanted to announce about Skyrim this month. I honestly knew Kinect Support was coming, but frankly, 2/3 of the install platforms can't use this, and of the 1/3 that can, probably Two-Third of that can't use Kinect because they didn't want to shell out for a gimmick.
conclusion:
Wasted energy that could be used to improve the game for everybody.
Bugfixes, Add-ons, performance
edit: it more sounds like MS told Beth to do somthing to help increasing the kinect sale.
