If Enix bothered to create two completely different games for 3DS and PS4 I will not be surprised if they do the same for Switch and PS5. Standard Switch can handle DQ 11 pretty well, nowadays engines make easier to scale down some games. I'm sure they will release DQ 12 (at least 2 years away) playable at least on Switch Pro. If Pro will really replace standard Switch 2 years in market will be enough to ship at least another 6 million hardware in Japan, so Enix will sell two versions of the game one playable on Switch Pro and PS4 (15-16 million japanese userbase) and another version targeting PS5 and PCs (3-4 million userbase in Japan)
This of course if they really want Dragon Quest to increase its current popularity in western markets like Capcom did with Monster Hunter World without lose market space in Japan
