I do not expect large-capacity optical media to become available for consumer use, but A 100GB BDXL can archive only 6 minutes of 8K video at 60 fps from a RED, so I would assume high-end visual production would want something better than 100GB per disk.

Sony will happily sell you ODA at 6tb per cartridge for $$$$.

I think the video production folk use LTO and HDDs for long term storage.

Everyone who still cares would like multi-terabyte optical - but it’s not a big enough market anymore outside of long term corporate archiving (the ODA use case), and Sony probably doesn’t want to canabalize that market.

Sony sells decks and recorders for their high-capacity "Professional Disc" that can hold up to 128GB per disk. And then there is their cartridge to compete with LTO, the ODA Gen 3 that holds, IIRC, 11 discs with a total of 5.5 TB per cartridge. A bit less than LTO-7 (and half as much as LTO-8), but I don't think LTO tapes can survive being boiled in water.
