Yes, that is the last generation of that "old" PS.
I must have hallucinated the countless hours playing all these on PS4. Excuse me, I need to go see a doctor ASAP.
(also Dragon Quest XI, Monster Hunter World, Dragonball FighterZ, Tekken 7, Nioh 1 and 2, Trials of Mana, Digimon Story Cyber Sleuth, etc.)
Everything after PS5's launch can be put into the new management and restructuring.
I doubt big japanese multiplats with big publishers will ever stop coming to all possible platforms, smaller devs or the ones looking for a publisher might not be arriving on PS anymore and instead steam.
I also don't see any more second party japanese productions for PS any time soon, the closest would probably be something like DS or some SE exclusive.
You are missing an important one tho:
