It has been rumored for a long time, but now it's official that South Park: The Fractured but Whole is coming to Nintendo Switch and we don't have to wait very long either as the release date has been set for April 24. There were rumours of South Park: The Stick of Truth also appearing on Switch, but that was not announced and it doesn't appear as if Ubisoft is planning any sort of bundle of the two games.
The game will be released at full price and the first pieces of DLC making up the season pass will be released alongside (but not included) the game in April. The third and final DLC, "Bring the Crunch" will launch this summer.
