Microsoft announced a few things on its press conference that are available to Dashboard Preview members now before they release fully this fall/winter.

Here Fred runs you through all those features and how they work – answering questions about game saves, achievements, functionality, and DLC on 360 titles – in a brief 10 minute video.
