According to a tweet by Xbox Live's Larry Hryb, Microsoft is rolling out an update containing "behind the scenes improvements" to a few select Xbox 360 owners this week with a full release next week. The update, version 2.0.15572.0, will reportedly place the Avatar store in the social pane in addition to creating a "Manage Exercise Info" field in the player profile for upcoming fitness titles. According to Hryb, the update will also lay the groundwork for future enhancements, such as Microsoft's Smart Glass technology, which was debuted at E3 last week.
