Only 35 games have broken 10 million.
25 of those were made by Nintendo.
They get about 1 per year. (Although it would be more accurate to say that during the NES/GB days they got 1-3 per year, and during the Wii/DS days they get 1-3 per year.)
2007 had Wii Play come to America and Wii Fit come to Japan. They'd already filled their quota of insanely successful games.
