A Twitter user posted what is claimed to be a sample from Kinect 2 running on a Durango (new Xbox codename) development kit. The image shows two users interacting with Kinect and what appears to be an increased amount of depth and movement data.
One of The Verge's sources says this is a genuine test sample. Microsoft is working with the Durango Xbox Development Kit (XDK) and the user interface is the same as shown in the picture, according to one person familiar with Microsoft's Durango work.
