I don't think Netflix or Netflix-like systems are where the future of home entertainment actually lies. Those things will be around, but, once the distributers actually wise up (and they are), they will self-distribute their catalog. I predict that you will have free access to a streaming catalog from each distributer and you will pay for access to individual films. Just like buying a DVD, you will pay 'X' dollars to have permanent access to a streaming copy of whatever specific title that you want. You will then be able to stream it to your roku box/iPhone/gaming system/built-in TV software/etc.
Don't believe me? The Green Lantern Blu-Ray comes with a digital copy of the film that does just that. Netflix proved that it can be done, now it's up to the distributers to actually release their own content. It won't change how your film viewing works at home except you won't have to go to Best Buy to buy them and you won't have pesky hard copies filling up your book shelves.
I believe, without a doubt, that this system or something similar will happen within 10 years.
