We’ve already had some time with the new Xbox Live Dashboard update, but now we have an official release date. The new firmware, which will bring Facebook, Twitter, and Last.fm to the console, will be available for download this Tuesday, November 17.
In addition to these services, Microsoft will be rolling out Zune Video, which promises instant-on 1080p video streaming as well as 5.1 surround sound.

We should note that Twitter, Last.fm, and Facebook will require an Xbox Live Gold membership ($50/year) and both Twitter and Facebook services require all users to be at least 18 years of age.

If you aren’t a member of Xbox Live Gold, a free preview weekend will begin November 20, at 12 p.m. ET and run until November 23, at 12 p.m. ET.
