Maybe in a few years they really will be able to get 4K film file sizes down to 100GB or so without too much compromise.

I could be wrong, but the regular flavour of AVC (never mind the claimed 50% efficiency saving of the eyeIO version used by Sony for their 4K download service) wouldn't have too much trouble bringing in a 2 hour 4K movie under 100GB using Blu-ray level bit depth and colour sampling standards.
