How is you AppleTV update? Oh wait, there wasn't one I'm telling you, they have redesigned the UI for ATV but we won't see it until Oct. iOS 7 was a lot on their plate for this rollout. The rumors of a co-release where sketchy.
The Apple TV update is out now. There is no new UI which was obvious since there were multiple beta releases showing no UI update.

What's new?
iTunes Radio and Airplay from iCloud. It lists some other things but I'm not sure any of them are new (except maybe purchasing of music?).
