Yeah. At bare minimum, I expect Square-Enix and Koei-Tecmo (Team Ninja, tri-Ace, and mainline FF notwithstanding) to be fully on board. Their Switch support has been stellar and I think it'll only get better, so long as the next system doesn't flop. I can see Capcom bringing Street Fighter 6 and its Resident Evil/DMC games (the ones that aren't on Switch, or were Cloud only) over to the next platform as well. Falcom, Marvelous, and NIS are shoe-ins.
No idea about Namco, Sega/Atlus, or Western teams, though.
