Disclaimer: I know that for most of this games is just guessing, still I would like to talk about it. For some of the games maybe you know if the developpers said anything about Switch ports.
I always considered buying a Vita, but never did it since nearly all of the games which interest me are exklusives and none of them are system sellers. With the Switch having the possibilty of having those games on a Nintendo handheld system where the 3DS couldn't because of it's weaker hardware I would like to witch of those games in your eyes probably will get a Switch release.
