Wii Music and Animal Crossing Wii are the obvious choices. I think those two are the potential 10M+ sellers of the upcoming games we know so far, and I think Nintendo are ready to pull the curtains back for both. So unless they have a really big secret game, I can't imagine what else could steal the show from those two.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
