What I’ve posted last year is actually starting to happen now. HD movies are starting to be sold online, with Sony being the first to market. They’ll be leveraging their PlayStation Network (PSN), which comes with every PS3.
The product is still defective at this time due to the DRM crippling, but by 2019 I think we’ll have that sorted out, too.
So something is starting. Where can I buy and download my DRM-free English-language Dexter episodes in 720p instead of the skullfucked and assraped German dubs in 720×576? It’ll still take some time, but I’m sure it will be possible eventually.
