We're receiving reports that Microsoft is updating opted-in Xboxes with the new Dashboard preview ... and it doesn't do much at the moment. The most noticeable addition is a new "Xbox Beta" channel, containing three new titles: "Xbox Beta Program - Preview LIVE Update," which isn't clickable, "New Features" and "Help and Tips."

The "New Features" tab, according to tipsters, notes that test subjects will be divided into two groups: those who receive the update online (and will receive their free Halo: Reach later), and those who will receive the update via disc. Microsoft also told users that it is "finalizing the logistics to distribute the discs now."

[Thanks to everyone who sent this in!]
