Nintendo is teaming up with mobile app developers Line Corporation and NHN Entertainment on the title.
It will be interesting to see how well Mario Kart Tour performs when it launches later in the summer. The original plan to release it during the previous fiscal year stands as a testament to that, despite the newly announced delay.
The news comes just six days after Nintendo told fans it was restarting development of Metroid Prime 4 for the Switch with a new studio because it wasn't happy with the progress made so far.
Nintendo is developing yet another mobile game, this time making Mario put on the lab coat he wore once back in the '90s.
Looking to the quality of Nintendo's past mobile efforts, this will likely be good news for players in the end. Nintendo has another hit on their hands, supported by excellent first-party games. If this is real, however, it does reduce the chances of there being a more powerful and expensive "Switch Pro" on the horizon, as it's unlikely Nintendo would do both in a single calendar year. The fall is the busiest gaming release season for big titles, in most cases, so a summer release window would slot it right between two blockbuster seasons.
