Remember when we told you Wednesday to not wait and sign up immediately for the Xbox 360 dashboard update public beta? Well, we hope you listened! Microsoft public speaker extraordinaire Major Nelson has amended the original post to let everyone know that the public beta has been closed, that all necessary slots have been filled, and that everyone who snoozes inevitably loses (or something like that). Those who successfully completed registration will be notified in the next two weeks. Don't fret too much if you did miss the opportunity; the new dashboard should be available to everyone sometime before the new year.
