I updated to the beta version of the fall update and found that Apple has already added Dolby Atmos to many movies, including some HD movies! I have read that they plan to add tons more. They are just getting started. This is a game changer for me since I am all set up for Atmos. Plus, you can enjoy Atmos even if you don't have a 4K TV yet, which I don't (planning to change that on Black Friday!). This is very good news! Now, since Vudu is my favorite, maybe this competition will spur them to do the same!
