According to the Australian retailer's list Sanity, who mentioned the game in their "Coming Soon" section with a release date of 13 MarchSouth Park: Dial-ups it could be coming up Nintendo Switch

The retail listings, on the whole, tend not to confirm anything, but Ubisoft has a long history of porting and remastered. South Park: Clashes Di-Retti, unlike the previous game, runs on the engine Snowdrop, which has already been brought on the Switch with Mario + Rabbids Kingdom Battleso there should not be any problems to make the game work.

We therefore await new information.
