What other games can Nintendo produce to sell over 10 million for Wii?

I find it funny we are debating which franchise could Nintendo use to make another 10+ million game. Yet the competitions platforms don't have a single 10+ million game. Unless you combined sales of a game combining the sales of both the 360 and PS3 versions. Only Nintendo can push so many titles to the 10-million mark but honestly other then Mario Kart the other Wii franchise based titles are in their own zone. Can more then MarioKart make the 10+ million mark without marketing it towards the casual gaming audience?
