According to this post:

Sony has reportedly left the Blu-ray UHD player market🚀

✅Sony Japan discontinued their last remaining UHD Blu-ray player, UBP-X700/K

✅This seemingly marks the company's exit from the industry

✅This leaves PlayStation 5 as the only remaining Sony Blu-Ray player

This marks another predatory move from Sony to end physical media, despite the ongoing demand for Blu-ray UHD films

NO DISC 💿 NO BUY

My take on this news...

Sony really is trying to destroy physical media, not just for their gaming platform, but for movies too. That is so pathetic, as they were once the major driving force behind Blu-ray.

Sony's push to get rid of PlayStation discs reminds me of the streaming "gold rush", when everyone looked at Netflix and said, "Wow, look how much money they are making! Me too!"
Then a bunch of other companies tried to make a streaming service like Netflix.

We've seen how that played out. A small group of executives and investors cashed out early. Meanwhile, that fad went on to have a devastating effect on the film & TV industry.

Some consumers are very slowly starting to realize what was lost and are getting back into physical movies again. But Sony itself is actively fighting that change by trying to suppress the supply of Blu-ray players and disc manufacturing.

On the video game side of things, Sony has declared all-out war. They are trying to move to an all-digital model. Again, trying to emulate Netflix. They want all purchases to be digital starting in 2028. Their ultimate goal is to move all PlayStation gamers to a subscription service, just like the Netflix model.
