The other thing you have to consider is you can say "well it'll be a pain in the ass to really tune the game for the Switch" ... and maybe so, but once they have the engine working on Switch, they can make 3 games out of it as FF7R is 3-parts.
So that right there is a pretty strong reason to want to do it. That investment will likely pay off especially if Switch sells well, which all signs are pointing to.
This is also why IMO it'll be on XBox One (and by extension Scorpio). Because once they build the engine once for XBox, they can then easily make three games from it.
Too much money on the table to ignore. This is a business. S-E is not going to miss out on 6 potential versions of FF7 (three each for XBox + Switch) just because Sony asked them to. My guess is Sony wanted exclusivity but Square-Enix said hell no. FF7R is also a good way to get new young fans into the Final Fantasy brand, which Square-Enix needs, so they can't be looking off all those XBox and Switch owners. It's their main brand, it would be like Activision making COD only for PS4 ... it would be monumentally stupid on their part.
