The PC burners/readers are disappearing. We had like ASUS, LG and Pioneer manufacturing. Pioneer had thrown in the towel last year (they were heads above the best in quality). I think ASUS might be gone as well. LG's drives are super hit or miss and I wouldn't be surprised if they give it up eventually.

This is probably due to the fact that they relied on Intel SGX security which has been busted wide open and itself been discontinued by Intel so instead of redesigning the security model, just depreciate the entire format on PC.

I don't think there is that much of a market left for set top players either.

Of all the companies you'd think are committed to the format, it would be Sony right?

Well they currently list one model of set top player on their website and it is the same design since at least the pandemic(when I bought my player). The SKu has changed since then but after looking at the differences, the only design update they have done in those ~6 years is upgraded menu software and removing built-in smart or networking features.

8K hasn't taken off as far as I know but eventually it might and right now there is no transition path to that for physical media.
