Sony have just filed another patent seemingly dealing with backward compatibility for game software
Simulation of legacy bus operation for backward compatibility
This was published on February 21st, 2019, so yesterday.
This is seemingly a continuation of the patent that they filed previously, and we had a thread about here.
No specific 'legacy systems' are named, so it could be referring to any of their old consoles. I'd speculate that were the PS5 to have architectural commonality with the PS4, this type of system would not be required, so perhaps the legacy devices that this is related to would be PS1/2/3. It would make a lot of sense to me that Sony would want to get legacy games running on one box, not just to sell people on a new console, but also because their new console hardware will be what the basis of any future streaming service is operating on, and to be able to offer as much content from their back catalogue as possible will be beneficial for driving subscriptions etc.
I don't think it's clear from these patents if we're talking about discs, or just downloads. Ideally it would be both.
Worth noting that this patent explicitly mentions 'Backward compatibility' in the title, which the previous one did not.

In order to deal with a problem caused by a bus operation difference when executing a legacy application with a new device, a new device emulates the bus operation of the legacy device and executes the legacy application You can adjust the bus performance when you do.
