Earlier today, Microsoft announced that they have not only released the 2.0 SDK for the Kinect, but they have also released a new adapter kit for PC users.
The Kinect SDK 2.0 is available today for you to download for free here. There are no fees for runtime licenses of commercial applications developed with the SDK. With over 200 improvements and updates to the SDK since we released the public preview in June, including enhancements to Visual Gesture Builder, Kinect Studio, and Kinect Fusion, we get you coding faster with a substantially more stable and feature-rich product.

Kinect Adapter for Windows. On Oct. 7, we introduced a standalone version of Kinect for Xbox One. We are extending the value for Xbox and Windows customers with the availability of the Kinect Adapter for Windows for $49.99 (USD). This adapter allows you to use the Kinect for Xbox One with Windows 8.0 and Windows 8.1 through a USB 3.0 port. Purchasing the Kinect for Xbox One sensor along with the adapter brings it to price parity with the existing Kinect for Windows v2 sensor. The Kinect Adapter for Windows is available in over two dozen countries and regions – rolling out later today – and will be available in a total of 41 in coming weeks.

If the Kinect is your cup of tea, you can find out more on today's improvements and updates at the Microsoft blog.
