Despite being the Nintendo Switch's second best-selling title, Mario Kart 8 Deluxe was a done-in-one game for the company. It brought the Wii U's Mario Kart 8, plus all of that game's downloadable content (DLC) over to the Switch, and called it a day. There were no additional releases for the title.
Until the end of last month, when Nintendo updated Mario Kart 8 Deluxe to work with Nintendo Labo. Players can build the Motorbike Toy-Con and use the control scheme to race in the game. It was an interesting and intriguing addition to Mario Kart 8 Deluxe and Nintendo says it won't be the last. In an "Ask Takahashi" segment posted on Twitter by Nintendo of America, Nintendo head of software development Shinya Takahashi promised more was coming to Mario Kart in the future.
"Now you are able to play Mario Kart 8 Deluxe using the Nintendo Labo Toy-Con Motorbike. So whether you’ve been using bikes in Mario Kart 8 Deluxe or not, please try playing with the Nintendo Labo Toy-Con Motorbike," said Takahashi. "There will be further updates for Mario Kart 8 Deluxe, so please look forward to it."
Whether these are more updates related to Labo, or more DLC featuring new characters and tracks remains to be seen. Mario Kart 8 impressed with DLC that moved outside of the Mario franchise and with Smash going all-in with Super Smash Bros Ultimate, it'd be nice if Mario Kart 8 Deluxe could get some more new racers.
