Mario Kart 8 Deluxe Dataminers Discover Future Booster Course Track Hints
Mario Kart 8 is eight years old at this point, with the game originally released on the Wii U in 2014 before being ported to the Nintendo Switch as Mario Kart 8 Deluxe in 2017. The Nintendo Switch port included both DLC add-ons as standard, adding characters such as Link to the roster. Currently, Mario Kart 8 Deluxe is the best-selling Nintendo Switch game, so it is understandable that Nintendo isn't in a rush to release the next entry in the series.
