There were several things that Microsoft left out of the conference and they got announced after the conference, during the interview.
-Avartar Store support is coming where you can get items for your Avartar via in game un-lock. You can get prop and accessories to go with your avartar.
-Full game download service. Microsoft will start to put full retail game on XBL Marketplace. It seems to be mostly old game but I think that's a perfect place for the Platinum games or older bargain games.
-Fanatec steering wheel is "officially" support by Forza 3 and they have the wheel set up and run along with Forza 3 demo.
-Xbox live will get rating system, where you can rate the contents on XBL marketplace. (Probably and hopefully similar to Netflix where you have to actually rent the movie or bought the item before you review, and hopefully nothing like Amazon or Metacritic where people can just randomly rate stuff.) If not I can see big abuse with the system. (this is why we can't have nice thing...)
