Hard to say.As people said, Mario Maker will probably kill the remaining legs of SMBU, but it still has to sell over one million to catch up to it.I personally believe it will, since Wii U still has a lot of time till it is replaced, but we will need to see.
My (locked) thread about how difficulty should be a decision for the developers, not the gamers.
