I think the idea of purchasing physical copies of films will be on the way out.

Bluray etc is great, but a 3-4gb H264/matroska file can provide reasonably comparable quality that would be acceptable to most.

And it's what other people have said - obtaining films illegally via streaming or download is (presuming decent broadband) more convenient and a better experience than buying the DVD, and that's the simple issue. No piracy warnings, no trailers, just the film. And you can store it on your HD and be watching it within 10 seconds - no digging around the back of a cupboard trying to find the disc, hoping it's not been scratched, and no listening to your DVD drive stopping and starting in the background while watching the film.
