If I remember correctly Nomura did say something along the lines that if a Kingdom Hearts game does come to PS5 it would most likely be when all the other big developers released most of the major game titles. So I believe it will be dependant on if there is still any major big projects by major game developers still in the works at that point and just how many as I’m guessing Nomura doesn’t want too much competition for his first PS5 release, so It’s hard to say. However given we will get “ good news in 2022” regarding Kingdom hearts I see it most likely that the game will come out on PS5 which I’m estimating we could get a game somewhere between 2022-2024 depending on how much work is done before 2022. However Nomura did say he doesn’t want to have a game take as long as it took KH3 to release again and wants them to come out quicker next time so that’s a good sign. Although I believe the next Kingdom hearts game will be on the PS5 I believe it will also be out on PS4 as companies will probably have to take into account the trouble people had getting a PS5 in the first place and the fact more console will need to be produced, so honestly not putting it on the PS4 doesn’t make much business sense to me as they would be losing out on a lot of money. Also if I remember hearing correctly I think Sony tends to support previous console and encourages games to be produce to about 3 years after current console release most likely more this time due to Pandemic.
