Nintendo is teasing the next tour for Mario Kart Tour with the image above. They also shared the following message with that image.
It’s a bit early, but here’s a sneak peek at the next tour in #MarioKartTour! We received a delightful photo from Rosalina and Daisy who just arrived at the next destination. Feel the gentle spring breeze as you race through this next city!
While we don’t have a definitive answer as to what’s being teased, it seems the prevailing attitude is that the tour will include the Netherlands in some way. We should find out if that speculation is spot-on sometime in the near future.
