Via the Official Nintendo Twitter, it was announced today that the mobile Mario Kart game ‘Mario Kart Tour’ will be delayed until Summer 2019.

Mario Kart Tour was originally scheduled to release in March 2019, but in their tweet Nintendo says that the game needs additional time to improve the quality of the app as well as work on developing post-launch content.

It’s still unknown what Mario Kart Tour will offer exactly, but if Nintendo’s past mobile games are a sign of what’s to come then we should be in for a solid mobile game.
