Vudu will have to react to this as their UHD movies are priced at $29.99. I hope I can stream 4k home movies through Plex on the new Apple TV 4k.
If they do not implement Dolby Atmos, that would be ridiculous. But most consumers don't have Dolby Atmos and I bet most consumers only use the speakers on their TV. Apple markets high end products but they typically don't cater to the high end AV niche like us. Many people will watch 4k movies on their 46" tv sitting 10 feet away which completely negates the need for 4k.
