OH WOW! That's super incredible - i'd estimated around 15GB for a 2 hour film

It would be total incredible as it would be a 4K BluRay killer for the few that are buying into that format. Although i'll be honest, I don't think the format will be around in two years time. All of the manufacturers except Panasonic have no interest in it. SONY has even pulled their more decent players in favour of the super cheaply made 700 which doesn't even have a quality 110-240V power transformer in it. Even more insulting is the amount of people saying that the player sticks on discs after a few weeks of use! But how crazy in 2018, having a disc that only plays on a cheap player in the corner of a room when the whole world i smartphone driven
Let's see although as much as I love my AirPods etc, Apple doesn't seem that interest in great soundquality - hence BEATS & HomePods - they probably wouldn't sound much difference with a HD lossless film soundtrack compared to Dolby Digital 5.1. We'll see. Maybe in time? I'd love to see iTunes films be the ultimate in quality.
