Nintendo has to market the shit out of this, heck, go as far as making a demo of it and give it for free in the shonen jump mag, any fan of naruto, one piece, DBZ, and the other animes (bobobo, etc) will be interested in this. Distribute the demo wirelessly from gaming stores, put gigantic ads in the train stations, push the game in the actual animes and manga, thats free and good advertisement.
SMB gameplay + Naruto + One piece + DBZ + Boboboobo Boobobo + Ichigo 100% + Death note (missing any? There's many characters i dont know in these new images)
How could it possibly go wrong? Heck, imagine if this becomes online...
