From IGN:
In addition to reversing its used game DRM policies for Xbox One, Microsoft has revealed that the console will no longer require Kinect to function. In our latest Ask Microsoft Anything, Xbox Corporate Vice President Marc Whitten revealed that Xbox One owners will be able to use all of the console's core functions regardless of whether the new Kinect sensor is connected. Naturally, many of the tentpole features of the new Kinect, such as player identification, voice commands, etc., will be disabled as a result, but players will still be able to play games and access entertainment content.
The news represents yet another significant revision to the company's next-gen strategy. Shortly after E3 in June, Microsoft announced that it had revised its plans to restrict used games and require a constant online connection in order for the Xbox One to function following backlash from the fan community. What remained unclear, however, was whether owners would still be obligated to have the Kinect sensor connected and, perhaps more importantly, what would happen if the peripheral became damaged or ceased to function.
