This seems like a no-brainer to me. While it hasn't been confirmed, Atlus and Nintendo have a very strong relationship, so chances of P5 coming for Switch seem high. This is a great thing since I can't think of many games that would work better as portable / home hybrids than Persona.
Take the game with you for grinding and persona fusing, and plug it in to your TV whenever you want to experience in more detail the flashy visuals and crazy story.
I'd get the Switch version of P5 day one, even if it comes later than the other versions. Who has considered doing the same?
Atlus showing support, and even hints of their desire to introduce the Persona franchise to the Nintendo audience:
