"After careful consideration, we decided to stop manufacturing the Xbox Kinect Adapter to focus attention on launching new, higher fan-requested gaming accessories across Xbox One and Windows 10," a Microsoft spokesperson said in a statement to Polygon. As for any plans to bring back the item in the future, the representative declined to discuss Microsoft's product roadmap, but said the adapter "will no longer be available."
But the Kinect Adapter has now been out of stock for months at the Microsoft Store and retailers such as Amazon, Best Buy and GameStop, fueling speculation that the company has discontinued the item. In fact, if you search for "Kinect" on the Microsoft Store website, the adapter doesn't even show up in the results anymore; we were only able to access the sold-out product listing from an old link.
As for the Xbox One Kinect itself, Microsoft announced in October 2017 that it had ended production of the peripheral. At the time, the company said in a statement to Polygon that "it is not the end of the journey for the technology" because, in part, "Kinect continues to delight tens of millions of Xbox owners." Today, however, Microsoft has fully closed the door to the possibility of new Kinect users.
