We've been hearing quite a bit about next week's Fall Dashboard Update for the 360, but Microsoft's finally ready to spill all of the beans. Obviously, the biggest update is the "Xbox Originals" downloadable Xbox games, but other improvements include enhanced online profiles, increased social networking, beefed up parental controls, improved menus, and our personal favorite: DivX support. As stated before, Xbox Original games, like Halo 1 and Fable, will be going for 1200 MS points (about $15), which is roughly comparable with your local game store's bargain bin. Also on the fiscal side of things, certain titles on Xbox Live Arcade are getting permanent price drops, akin to "Platinum Hits" of retail titles. As for DivX, Microsoft was a little vague when speaking with Joystiq about it, but it sounds like XviD is in play as well, which is just double fun. It's all hitting as a free download on December 4th, starting at 2AM PST.
