Wii Music's critical and commercial failure were still relatively fresh, Shigeru Miyamoto mentioned that "there may still be some possibility" of continuing the franchise. In a recent interview with Techland, Miyamoto went a bit further, explaining, "There's a lot of potential still in Wii Music, I think. Because we're going to change it up, a new interface is coming, and all of that." Them's sequeling words, partner.
Miyamoto also addressed the possibility of Mario making an appearance in a Wii Music follow-up, stating "If we get more people to understand what's going on in the game concept, then he might appear in the game. I don't know." He added that a Mario cameo is somewhat unlikely, as "he can't play guitar" or saxophone using his stubby, gloved fingers. That's a good point, Mr. Miyamoto -- we guess he can't play too many instruments. But he can rap with the best of them.
