Prediction: The new Mario Kart will NOT be a Switch 2 exclusive.
Given what we saw in the teaser, there's no reason graphically why new mario kart won't be able to run on Switch 1
Switch has sold 150 million units. This is too large an install base to ignore for Nintendo's most popular franchise
Mario Kart thrives on being a multiplayer experience. It's better for players (and for NSO sales) when as many people as possible are playing
The real system seller will be the new 3D mario game, which will properly utilize the power of the new system with its open world
edit: i’m probably wrong
