steve98:DjShadow: Is there even a Blu-Ray standard out for 4K?
No. Extremely unlikely there will be a physical medium for 4K - likely to be digitally delivered only.
I'd beg to differ...
New DRM isn't too far around the corner, and odds on it will be a tough one to crack.
If they can make the DRM work, then content creators / distributors will make a physical disc and it will be a success. Without the DRM, content providers will walk away from the idea, meaning we won't see progress and high resolution as the norm will remain a pipe dream.
Watch this if you have time... the first part isn't necessarily related, but there are some nuggets of info in there.
