I hope ATV will get 5.1 support at MW in Jan. Besides all the other goodies we all want. Like buying directly at iTunes, I think 5.1 support is a must for ATV. It can already play 720p Anamorphic content. We're just missing DD support from Apple.
5.1 would be great, but there might be some kind of fee for DD licensing or something?
