Sure it matters. There are tons of unanswered questions on UHD Blu-ray, HDMI 2.0 and HDCP 2.2 and how they will all work together and how they will work with existing devices.
What happens when a consumer buys a shiny new UHD Blu-ray player and a bunch of shiny new UHD Blu-rays then plugs it all into their non-UHD / non-HDCP 2.0 compliant displays and/or receivers? If I remember correctly, analogue and component outputs functioned just fine with Blu-ray on release even though they couldn't support an HDCP handshake but to ship Blu-ray and not allow it to function in the existing ecosystem of devices would have been disastrous.
So, how will that be handled? Could it be like a Dolby Digital Plus stream which uses extensions where an older receiver can decode the 'core' 5.1 stream and newer receivers unlock the higher quality extensions? If so, what will be the 'core' of a UHD Blu-ray? Could the 'core' be treated as the maximum of HDMI 1.4b; 2160p24, 8bit, 4:2:0? Or perhaps the 'core' would be downgraded in resolution but retain the colour qualities like 1080p24, 10 bit or 12 bit, 4:2:2 or 4:4:4?
Perhaps, like Blu-ray, UHD Blu-ray could be introduced with a grace period during which non-HDCP 2.0 compliant devices would function?
Maybe it will be like HD-DVD where the first generation of players output 1080i, not the full 1080p that was on the discs?
Finally, when HDCP launched with Blu-ray, it was cracked within days allowing people to rip Blu-rays to their HTPCs. You could also acquire intermediary 'black boxes' which fooled the players into thinking they were getting a successful HDCP handshake.
However it is handled, I am very curious about the full capabilities of JVC's new line of projectors.
