Here is the article from TWICE : http://www.twice.com...-ray-way/109597
The very high data-storage and transfer-rate requirements of 4K/UHD – four times the spatial resolution of 1080p HDTV – means that optical discs will once again be the most practical way to move all that data around in a very convenient way. Blu-ray had a tremendous impact on HDTV adoption, and we think it will offer the same push for UHD adoption.
I know that streaming GOOD quality 4K content is going to kill many users with most ISP having bandwidth limitation, download caps.
Streaming, even in supposed HD, is far from the quality you get from a Blu-Ray. The compression level is so high, it often ruins the "HD" experience. I've tried "HD" from Apple, MS and Netflix and it pales (sucks!) in comparison to Blu-Ray. To me, it's worst than saying that a 128kbit MP3 is just as good as a CD.
