Nintendo don't usually reveal their development budgets, do they? They wouldn't be listed if we didn't know the budget.
It wouldn't surprise me though if they really haven't made many $50m+ games. Unless you're creating something incredibly ambitious (like GTA5), need development to move along quicker than normal or are simply setting fire to money, there's rarely a need to spend that much on development. They could often do with spending more on marketing though :p
