Yeah I just couldn't imagine South Park of all games on a Nintendo Console xD.
South Park games actually used to release on Nintendo 64. The last few skipped Nintendo consoles though. I just feel like Ubisoft might do it since it would be an easy port due to the game's graphics. That being said, Nintendo might want to censor it and I'm sure that Ubisoft won't put it on Switch if they have to censor it.
