Nintendo generally publishes 4-5 "big" games for a platform in a "big year" (usually the 2nd or 3rd year of a console/handheld).
This is their peak output generally.
After that they sorta become exhausted and need time to recharge.
In a slow year you maybe get 2-3 "big" releases.
Fact is there's only so much one company can do. Even though Nintendo's expanded a lot too, the loss of Rare has cut down on the amount of the games they release as Rare could often provide Nintendo will 2 good exclusives yearly (sometimes even more).
