Zune HD users should be pretty happy to hear that firmware v4.5, first leaked in January, is "coming soon," and will bring native XviD support to the device as well as streaming Smart DJ.
Smart DJ playlists, a "Genius"-esque song playlist creator, will also be available on the player and not just the desktop software.
If you are connected via Wi-Fi you will be able to to create Smart DJ playlists that incorporate streamed content from the Zune Marketplace, besides the songs already stored on the player.
