The next Xbox 360 dashboard update, which will include Facebook, Twitter and Last.FM integration, is going into public beta later this month, according to a Microsoft representative at today's Microsoft Open House event in New York City.
Jennifer Puzio-Brookes, an Entertainment Manager for Xbox, showed off the update in a behind-closed-doors session, and it seemed to include all of the major features promised in Microsoft's E3 press conference. Puzio-Brookes mentioned that a public beta will be released "middle-towards-end of October."
Like the last dashboard update public beta, this one will include invites to certain members of the Xbox community. There will also be early access to the new features for members of the press, but the exact timing for that access hasn't been locked down.
Check back soon for impressions of Facebook running on the Xbox 360. For real this time (unlike that canned Felicia Day demo).
