Nintendo of America representative Buddy Roemer has told Youtube user Super Shadow Hero E3 that Nintendo has no plans to patch the popular glitch on Mario Kart 7′s Maka Wuhu. Roemer said that Nintendo were aware of the glitch but there are no plans to actually update the game to remove the glitch.
Thanks for your patience in waiting for a response during this busy time of year. We are aware that it is possible to navigate a certain part of the track in Wuhu Island in a way that allows a large part of the course to be bypassed. There are no plans to update the game to remove this shortcut as doing so would create an unfair advantage for the users of the original release of the game. Rest assured your comments have been added to our records for Mario Kart 7.
