Xbox Dashboard update preview invites out this Friday

Major Nelson, Xbox Live guru and prolific tweeter, has announced that the first wave of notification emails for the Xbox 360 Dashboard update preview should go out this Friday. Incidentally, sign up is now closed, so no more applications will be accepted. The preview will give Xbox Live members a chance to check out the many new features in the upcoming Dashboard update, including Twitter, Facebook, Last.fm and the new Zune Video Marketplace. Also, as we reported earlier today, Microsoft has thrown in a preview of Halo Waypoint as well.

The preview program should roll out sometime next week. In the meantime, keep an eye on those inboxes!
