It is awesome that HDMI 2.1 will support native 8K video with 48Gbps cables, however it could be 2026 before an 8K optical disc format is released (With 10GB per second residential Internet, 8K downloads and 8K streaming might prevent a 8K optical disc from being released). The 4K Ultra HD Blu-ray format might end up being the last and best optical disc format before streaming and download takes over.
If we start seeing HDMI 2.1 displays and A/V receivers in the future that offer 8K video support then you will know that native 8K movies will be coming a few years later most likely (VUDU and Netflix 8K interfaces will try and kill the 4K Ultra HD Blu-ray format).

I am not sure if I get the need for the new spec. Uncompressed 8k60fps 12 bit color is 76 Gbps, or 9.5 GBps (8192*4320*3 color * 12bits per color *60fps) . Double that for 3D. So you are not going to be doing UNCOMPRESSED 8k over the cable, but there is PLENTY of bandwidth for compressed in HDMI 1.2. But as I said before, TosLink has plenty of bandwidth to do Dolby TrueHD and DTS MA, so I just learned to say "whatever" when these new specs are announced,

HEVC is pretty amazing from what I can see. Pretty sure VP9 will be just as good.

The immediate benefits to HDMI 2.1 are two fold:
1. Supports 4K @ 120 FPS
2. Supports Dynamic HDR
One movie has already been shot at 4K @ 120 FPS. It will be up to Hollywood to adopt this format. The chances are not too good as Hollywood doesn't seem to like high frame rates
As good as today's HDR is it will be much better in the near future when Dynamic HDR begins to be used.
