This Fall like previous ones, Microsoft is giving the Xbox 360 a new update. The Update will give some UI changes and a few new apps and an updated Netflix. New apps include ESPN3, where you can watch live sport events and their replays (in HD). Some ISPs don't support it right now, but Microsoft says they are working with them to allow it. There is a new Zune Music app coming, which is great for Microsoft and Zune because it will introduce more people to their awesome PMP. The Zune Music app will have Smart DJ, playlists, and Zune Pass online streaming. The new UI tweaks are from the WP7/Zune Metro UI, everything is flat and has sharp edges. Avatars also got an update but it is just in the menu to create and edit them. The Netfilx app also got a UI update that falls in line with the rest of the new UI. Searching and streaming right from the app is also going to be there. They also added new ways to move around the UI with Kinect but you will need one for that feature(which will release same day, November 4th.) Engadget story
Look for it soon.
