Kinect, which allows players to play games hands-free, will be released in Europe on November 10.
The announcement comes before Kinect's European debut at this week's Gamescom in Cologne.
Speaking before the event, Microsoft's Chris Lewis said: "With Kinect launching on November 10, it’s set to not only transform our business but also change how we use entertainment. With Kinect, YOU become the controller, giving you the choice in how you and your friends navigate entertainment and gaming experiences.
"We’re already seeing a high level of anticipation in Europe with sales of the Kinect ready Xbox 360 250GB creating an all-time record weekly market share."
Microsoft will use the event to unveil new modes in games such as Kinect Joy Ride, as well as new events in Kinect Sports.
