That email purportedly sent out by Microsoft a couple weeks back inviting its recipients into a Kinect beta program? Yeah -- it was legit. Joystiq has received corroborating evidence confirming the program, including pictures of the promised Kinect-enabled Dashboard update running on a participant's retail console. In them, you can clearly see the flatter presentation, new mini-guide and revamped Avatar editor -- complete with a re-proportioned Avatar.
Our tipsters clearly didn't read the included guidelines, pictured in the gallery bellow. Apart from the laundry list of methods via which participants aren't supposed to talk about the program, there's confirmation that Kinect hardware is indeed part of the beta, "is being packed" and will presumably be on its way to testers soon. These same sources report that the beta support site mentions Kinect Adventures, Kinect Sports and Kinect Joy Ride as titles they can expect to receive for testing purposes.
We'll have more on the program as its participants continue to refuse acknowledgment of Microsoft's terms and conditions. [Update 8/27, 9am: And we've got a video of the new Dash posted just after the break, featuring much more than the boot-up screen. Thanks, Bradley!]
