1. Stats from industry analytics firms are next to useless. They're often made up.

2. "Blu-Ray" local streaming has been available, commercially, for a few years - even with the atrocious and pointless BR menus. You won't see internet-based super-high bit-rate streaming for a very long time, if ever. Not because it won't be technically possible, but because there's no demand for it and unlikely to be any future demand.

3. No amount or variety of copy protection is going to stop a dedicated individual from ripping their media, Blu-Ray or otherwise.

4. If you can't see the difference between 720p and 1080p then you may not be using a high quality display, are using a small display or are sitting far enough away not to perceive a difference. BTW, there's no 24 fps 720p format - for many people 24hz frame rate is reason enough to use 1080.
