Unfortunately Nintendo was unable to confirm if the game is coming onto the Nintendo 3DS handheld console or if it will be destined for the Wii U instead. According to the game’s producer, Yoshiaki Koizumi when asked about which platform it would be released on, he said, “That’s still a secret. I can tell you, though, that we’ve already started approaching our next challenge.”
However the game’s team leader, Kenta Motokura seemed to hint that perhaps it could be for the Wii U because he mentioned that if it were released for the Wii U, the game might take advantage of the GamePad to help enhance the gameplay. In any case we guess we might have to wait a while until we learn more about the new Mario game, so until then stay tuned for more updates!
