The folks over at Nintendo EAD Tokyo are currently hard at work on a new Mario title. Go figure.
When asked by Edge in a recent interview what the team had planned next, Nintendo producer and Super Mario Galaxy director, Yoshiaki Koizumi, confirmed that a new game starring everyone's favorite pipe-traveling plumber is currently in development, but wouldn't provide any additional details.
In fact, Koizumi wasn't even willing to discuss whether it was coming to either Wii U or 3DS. "That’s still a secret!" he explained. "I can tell you, though, that we’ve already started approaching our next challenge."
