I doubt they'd remove Kinect until well after launch. They will sell out at launch. If they need to boost sales later, a cheaper, Kinect-free kit would do it.|
The concept that Super Kinect will be integral to any core game on the thing is just ridiculous. Any dev working on it should have their game able to work Kinect free simply to deal with an expected failure rate, let alone people who will throw a blanket over the thing.
