The official Kinect for WIndows SDK is out and you can grab it here:
http://www.microsoft.com/en-us/kinectforwindows/develop/overview.aspx
The key points are:
- As long as you use a Kinect for Windows sensor (not the XBox360 one) and the official SDK, you can develop commercial applications using Kinect technologies.
- New near mode for depth values (no skeleton tracking in this version) which enables the depth camera to see objects as close as 40 centimeters
- Up to 4 sensors can be connected to the same computer
Alongside with the SDK a new sensor is available. If you want to buy it ($249.99), you can go there:
