Mario Kart 9 (Nintendo Switch)

Mario Kart 9 is an upcoming Mario Kart game for the Nintendo Switch that will be the follow-up game of Mario Kart 8, a Wii U title, and Mario Kart 8 Deluxe, a Nintendo Switch title. It will also be the second Mario Kart game for the Nintendo Switch.

A prominent new addition is jetpacks, allowing players to zoom as fast as they can. Elements from Mario Kart Wii, Mario Kart 7, and Mario Kart 8 are reused, such as Bikes and 2-Player online from Mario Kart Wii; and gliding, underwater driving, and kart customizing from Mario Kart 7; and anti-gravity, DLC, ATVs, and Mario Kart TV from Mario Kart 8. In addition, planes join the returning karts, bikes, and ATVs as a new class of vehicles.

Unlocking criteria
Like Mario Kart 8, characters are unlocked at random by completing cups where fixed characters were unlocked by completing specific cups on specific engine classes in many cases but, a new character cannot be obtained if the same cup is played in the same engine class again; for example, if the 50cc Mushroom Cup is played and a new character is unlocked, then another character cannot be obtained from the 50cc Mushroom Cup. Additionally, unlockable characters appear as CPUs during races when they are not yet unlocked, making this game the second Mario Kart game to do so.

Courses
There are 32 tracks consisting of 16 new tracks (so far) and 16 retro tracks. As with the retro tracks from the Wii U and Switch installment, the retro tracks in this game features altered sections that incorporate the game's hang-glider, underwater, and anti-gravity features. The game features live-recorded music for the new tracks and the retro tracks. Nintendo also announced that there will be DLC courses as well. (and yes, that means DLC courses from the Wii U game will appear as well)
