The new Xbox 360 Dashboard update is available to a select few who decided to enroll in the program. Much of this update also works in Kinect, including adding entity "Kinect Settings" under system settings. The Dashboard update also features Metro updates to applications, and a new one, ESPN which'll allow users to view over 3500 sporting events directly from their Xbox 360. Other new features include an updated "My Xbox" when you select your gamer tag. Presented to you now is the original main screen for your account, but just one tile over you have easy access to your Account Management, which shows information about your account including Membership, Points, and the Windows Live ID. Another tile over has privacy, and then from there on out it is all about the games and your achievement progress.
Zune has been updated as well, which is very much akin to its PC counterpart.
