Microsoft has finally seen fit to release the details of its Xbox 360dashboard update. Scheduled for release the morning of October 31st -- yes, that's tomorrow -- the update will add the much-talked about 1080p / HD DVD support, as well as the ability to play WMV files from a connected PC, disc, or USB storage device. Currently, users can only stream video from connected Windows Media Center PCs, but any XP machine running Windows Media Connect or Windows Media Player 11 should be able to do it post-update, as demonstrated during a press conference in Japan with several 720p-encoded videos. This compares to the PlayStation 3's recently-revealed compatibility with MPEG-4 and other video files, but so far neither has announced support for DivX / Xvid and Media Transcode 360 still requires Media Center. Apparently only 84 things needed fixing this time, down from the 125 in the spring update, including the option to automatically download demos of new Xbox Live Arcade titles, Zune media streaming, wireless headset support, XNA Game Studio Express and numerous improvements to video playback and menu handling.
