NSMB games are generally very popular and they selling very good, NSMBU+L is probably best NSMB game, plenty of people didnt played game on Wii U, and last point games and especially Nintendo games are generaly selling very well on Switch (definitely better than on some other Nintendo platforms).
With all that on mind, yeah, I think it will hit 10m, and I dont think that legs will be cut too much even with next 2D Mario that will probably be Mario Maker 2, simple because 2-4 player co-op fits great for Switch with one or two pars of Joy Cons (from same reason I think they will port SM3DW also).
