If we where talking dvd quality the internet can offer that quality with no problem IMHO. But as far as 1080p content goes the quality is all over the map and while downloads may come close to bluray it generally doesn't offer lossless audio with the HD content. And streaming is not as good as bluray hd IMHO. So since the average person not having enough bandwidth in some cases to handle high quality HD streaming over the internet. How many people are going to be able to stream or even download 4K movies? How will the stream it without enough bandwidth and how will they download 4K content without it taking 10 hours or more? Alot of the just good enough crowd will not even bother because there internet is not fast enough anyway but more importantly the view there dvd or bluray as more than good enough. But the fact remains with the extremely large file size that 4K will use for the foreseeable future physical media will be the most reliable way to deliver a true 4K movie! Just imagine the data requirements of 8K and what it would take to get that content to consumers using the internet. Meridian is says they have a new system for improving audio quality for music formats to fix what the low quality mp3 has done to the quality of music. But how will studios get 4K to consumers with superior audio and video? There is only one answer physical media and I think unless studio really push to kill off physical media the deliver requirements will keep physical media viable for the foreseeable future.
