Unveiled at an E3 keynote, Microsoft has bestowed upon us a pair of new and heavily requested Xbox Live features that will come with the update. It should now store saved game info and a full Live profile. This allows you to hop to another Xbox 360 and resume progress without having to start from scratch.
Beacons are also new and show your friends your desire to play a game. Individual titles can be marked with beacons and will show up as interested parties on Live, even when you are playing something else. This lets gamers kill time with a game or a video until friends are ready to play with each other.
