I'd say that I wouldn't be surprised anymore if Persona 5 comes to Switch. The Switch is the biggest thing in the (non-mobile) gaming industry in Japan and is continuing to sell well overall worldwide. Persona 5 is still trending in Japan. Joker is coming to Smash Bros. Ultimate and, outside of Cloud, who's main game eventually will release on a Nintendo hardware for the first time soon (Switch), all of the third party characters who were invited into Smash have made a presence with main games on Nintendo consoles. Hell, even Ritcher's game, Rondo of Blood, was released as a VC game on the Wii Shop Channel (RIP), in its original JP format, overseas.
