The Xbox Kinect sensor bars will be released on November 3rd at midnight. However some people have already received their Xbox Kinect games but are unable to play them because Microsoft has not yet released the dashboard update that supports them. When they insert the game into the Xbox it displays an update error because as of right now you need to be in the beta program to get the appropriate update.
The person that actually reported this on Kotaku said it had locked their Xbox but not bricked it. The game happened to be Kinectimals. So I would assume that the error message stays displayed now until they get the update on the 4th of November or sooner. Be warned, unless you don’t want to use your Xbox till the update arrives don’t insert a Kinect game yet.
