4K would make all of this even more of a problem and thus noone in Hollywood really wants it, IMHO.
I kinda hope you are right. The reason being that I just switched to a 4k camera and did two shoots with it, and the results are so much better than 1080p to where even viewing the 4k content on my 65" 1080p plasma paints a remarkably better picture, far better than what DirecTV offers. What amuses me is how I on my own am now able to provide my customers content that looks sharper than what multi million dollar corporations can. So I do hope you are right and Hollywood shuns 4k as that would be fantastic for me, it would be great if people had to turn to internet websites like mine to for best picture quality. I suppose in a way that's inevitable though as my customers already have > 1080p displays available on their ultrabooks, tablets, etc so the transition to 4k is a natural one.
