I think Mario Kart 8 will do about 8 million LTD (and MK7 will probably top off around 12-13 mill).
Smash will be less than that.
Nintendo really needs a new franchise to break out for them and drive hardware sales but they're kinda hamstrung as much of their development resources are tied up working on iterative sequels.
