PS4 Pro will probably run UHD Blu-Rays via an update in 2017

Well depends how they encode the video i guess if they use H265 there is no valid reason as to why a movie should be over 50gb lol. Anything larger is just being lazy at encoding.

So in theory a firmware upgrade could potentially play dual layer discs.

Unless there is some sort of mechanical restriction when reading dual layer UHD discs.

Makes sense for 3-4 layer discs for this not to work.

No. HEVC roughly cuts the size in half but you have 4 times the amount of pixels. Nothing being lazy here.

It is being lazy. This stuff does not need to be 40-80 Mbit/s bitrate but closer to 10-20 Mbit/s will do. But to get it looking as good as 40Mbit/s you need more processing to encode it which takes longer.

A quality 2hour30min video at 1080p can be compressed to 5gb or so @ 5Mbit/s in h264.   So lets times it by 4 to represent 4K that is 20GB, double it for 10Mbit/s to 40GB. Then remebr this will be encoded in HEVC which is about half so lets assume 20GB. So 20Mbit/s would be 40GB, that leaves 10GB for audio.
