Of course it will. There's probably two games already out that will eventually hit it (splatoon and mario party). We know of two games this year that will be 10+ million sellers (pokemon, animal crossing). That's 9 right there. Throw in at least one more pokemon game, an actual new 2D mario game at some point, another 3D mario, and that's 12. And we will probably see a couple other games beat it as well. I think 15 would be a great goal to hit.
