Sony bought the rights for the physical releases. I was thrilled to see that the holy grail of Pink Floyd that was never released on record was the first announcement from Sony. Hopefully they will release more things, especially now that AI technology an separate recordings, so that they can clear them up and remix them later.
The only issue with the Sony re-releases, of the basic back catalog, seems to be the new very high prices. Hopefully they will come to their senses and lower them considerably.
