They won't disable it, they're excited about it. The fact that the Kinect can do other things is probably a huge attribute to its sales.

Kinect was not actually hacked. Hacking would mean that someone got to our algorithms that sit inside of the Xbox and was able to actually use them. Which hasn’t happened. Or, it means that you put a device between the sensor and the Xbox for means of cheating, which also has not happened. That’s what we call hacking, and that’s what we put a ton of work and effort in to make sure doesn’t actually occur.
What has happened is someone wrote a open source driver for PCs, which essentially opens the USB connection, which we didn’t protect by design, and reads the inputs from the sensor.
