With a range of new power-ups introduced in Super Mario Bros. Wonder, Mario Kart 9 now has the potential to adapt some of these as new items in ways that could turn the Mario Kart formula on its head. As Mario Kart 8 Deluxe anticipates the release of its sixth and final wave of its Booster Course Pass for 2023's holiday season, Nintendo has already confirmed that a new Mario Kart game is in the works. This has led many fans to begin speculating about what a prospective Mario Kart 9 would be like after the high bar set by Mario Kart 8 Deluxe and its DLC.
