You'll have to pry my Blu-Rays from my cold dead hands.
There is just no way I'm willing to pay an a la carte fee (many times $6 or $7) for an inferior a/v presentation with no extras that may cut out at any time, when I can just wait for Amazon discounts to bring most BDs down to $10 per movie, and an even better dollar-to-hour ratio on TV programming. No time limits, multiple viewings, the option to resell if I tire of it, and a superior a/v presentation.
As long as there are rational consumers who prioritize quality, and as long as broadband internet remains in its current fractious, terrible state, physical media will endure.
