Anytime between April 2012 & December 2012.
There is no release date set for it yet but it will most likely be some time next year.
Project Natal's official new name is Kinect. Kinect will be released on November 4th, 2010 and will cost $150(US) (unconfirmed price). Existing Xbox 360 consoles will be compatible with Kinect but will require an adapter. All new consoles will not need an adapter as they have a special port specifically for Kinect built-in the system.
The expected release date is apparently the 10th of November - It will retail under the name 'Kinect'
November 4 2010
Kinect will be compatible with ALL 360s - even those bought on the release date. If you don't have a new 'slim' 360, Kinect will require a power cord. The new ones have a special port that will power the Kinect. - Brunei Gamers
