They should probably wait until they have a better cast of characters to base a Kart Racer on, but man it would be amazing to get even more competition in the genre. Coming from them, they'd likely place a big emphasis on the Adventure Mode like in Diddy Kong Racing, so I hope it gets made. Wouldn't be against the Splatoon-like shooter either.
"Creo que continuaremos trabajando en Yooka Laylee en el futuro. Realmente podríamos trabajar en cualquier tipo de videojuego, como uno de carreras a lo Mario Kart o un shooter a lo Splatoon
Nunca hemos pretendido que Yooka y Laylee fuesen los protagonistas de todos nuestros juegos. Para el futuro, podríamos hacer un spin-off con uno de los muchos personajes que aparecen en Yooka Laylee, como Dr. Quack o Dr. Puzz
Ser independientes nos permite seguir el camino que queramos y el que creamos más adecuado"
"I think we'll keep working on Yooka Laylee in the future. Really, we could work on any kind of game, a racing game like Mario Kart or a shooter like Splatoon. We've never intended Yooka and Laylee to be the protagonists of all of our games. On the future, we could make a spin-off with one of the many characters from Yooka Laylee, like Dr. Quack or Dr. Puzz. Being independent lets us follow whatever way we want and the one we think is right."
