Its hard to believe that we are still waiting for a direct sequel for Mario Kart 8 about seven years later following its release back in 2014. The closest thing to a direct sequel for Mario Kart 8 was the World Tour mobile game from 2019. Mario Kart: World Tour is seen more as a spin-off game than anything else and was not nearly as exciting as Mario Kart 8: Deluxe from 2017. Not only is Mario Kart 8: Deluxe the best selling video game on the Switch console reaching over 38 million copies in sales; but Mario Kart 8: Deluxe is the most successful entry within its entire series. At this point Mario Kart 8: Deluxe is like the GTA V of the Mario Kart series in relation to popularity and overall success. Its quite possible that Nintendo did not expect Mario Kart 8 along with the Deluxe Edition to become this successful. Even if Nintendo were to develop a Mario Kart 9 its hard seeing the game potentially having more success than Mario Kart 8 along with the Deluxe version of the game. The Switch console has been around for almost five years now; most people are now under the impression that we might not get a sequel for the Switch console. Some believe that a potential Mario Kart 9 game should be saved for Nintendo’s next generation console; which is most likely going to appear sometime during the mid-2020’s decade. But then we have no idea on how long the lifespan of the Switch product line is going to last in retail.
