The Xtion Pro Live by ASUS is similar to Microsoft's Kinect hardware. The hardware includes a depth sensor, RGB camera and set of microphones. The device is aimed at development and is powered through the USB 2 connection rather than requiring an addition power connection like the Kinect. Its also slightly smaller than the Kinect.  I Heart Robotics has received one and they have additional information here.

Currently its only available for purchase directly from ASUS and is currently on backorder.
