If we compare PS4 vs the Switch I agree with you PS4 clearly had better overall Japanese support. The big AAA games will never be on the Switch's current model. So while something like Final Fantasy theoretically would be a great fit for the system it would never be able to run it.
Personally in this gen, I feel like all the big JRPG franchises except for FF and Nier will be on the Switch. But the more action and demanding games Souls, FF, DMC, etc will still be on PS5 first.
But these companies might follow what Monster Hunter did and make a game just for the Switch because it would be silly to ignore the install base the Switch currently has. Which probably is the biggest after 3 years since the PS2. (Not counting the Wii that shyt was casual heavy) Persona is the most interesting one to me in this regard do they keep making it Sony exclusive? (I know P4G is on PC, but that has been the one exception)
Yeah, it's not even all AAA games either. A lot of B, A, AA or whatever letter grade they can be classified as, weren't on Nintendo systems. It's been that way for like 4 generations, for a number of reasons, lol. They've opened up a bit more, more to indies than anything, which is fine and well since a lot of indie games are perfect for portable gaming.
I don't believe that "hardcore/serious" gamers have to own absolutely every platform, but if one played a lot of games heavily or wanted to, especially more hardcore games and could or only chose to own one platform, Nintendo would not be that one.
