Never say never, but for the meaningful future, optical discs will be the lowest cost mass storage media for retail sale of audio/video recordings.
There is a LONG way to go re: optical disc storage capacity to handle 8K (Or higher) video formats.
First, BluRay may be able to handle more layers, currently at 33GB/layer for UHD discs
"Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives"
Most 1080p BD discs were 25GB/layer single or dual layer.
Second, there are plans for even higher density optical disc tech
1TB per disc: Sony and Panasonic team up on next-gen Blu-ray
Next-gen optical disc has 10TB capacity and six-century lifespan
Molecular/holographic "optical" disc has already been sent to space for human archival purposes
SpaceX Hid a Second, Secret Payload Aboard Falcon Heavy, And It Sounds Amazing
Arch is the company behind this new optical disc tech
Third, the HDMI road-map shows that HDMI 2.1 supports 8K 4:4:4 color sampling at 12 and 16 bits/pixels (vs 10 bits/ pixels for all current UHD discs) and 60 or 120Hz framerates, up to 127Gbps datarates (try that on throttled connections)
(see tables, scroll down)
With ongoing Net Neutrality and data cap/throttling issues, I think there's room for at least *one more* disc format- 8K 4:4:4 16 bit/pixel @60/120Hz
That said- been buying up all the UHD discs that interest me
3D disc sets, too...
I'll take almost any 4K UHD disc set that equates to ~$5/disc.
