The Xbox spring system update will be delivered to "a few" Xbox Live members this week, according to a tweet from Major Nelson. The update will be deployed to all members next week. Before you go rushing to check your Xbox, don't get too excited: Major Nelson noted further that the update will only add "behind the scenes improvements and prep for future enhancements."

Presumably, he's referring to things like Xbox Music and SmartGlass, which Microsoft unveiled at E3, and more video apps.
