Does the xbox 360/kinect have any yoga games yet?

I bought an Xbox 360 w/the Kinect sensor and have been looking for a yoga game for it. I heard something on a couple websites about a Cirque du Soleil-inspired yoga video in the works but I have no idea if it’s true. So far, the only yoga I’ve found for the Kinect is via the Your Shape: Fitness Evolved game. Can anyone shed any light? Thanks :)
