Looks like Kinect is a little hotter then some thought. GameStop claims it is Sold Out of the Kinect Sensor at the moment allowing no more pre-orders to be taken. They only have the Xbox 360 4GB or 250GB Console with Kinect bundles available for pre-order.
Newegg is also showing they are Sold Out of not only the Kinect sensor but also the Xbox 360 4GB Console with Kinect bundle. Could Amazon be next?
