No. Brawl sold 11.5M, which is by far the most any in the series has sold. I also think the franchise peaked with Brawl, I can't see interest being as high for a sequel. Especially since sales will be cut into by the game not being exclusive anymore, a 3DS version is coming out too. So I would say somewhere only 6-8 million for the Wii U version.
I describe myself as a little dose of toxic masculinity.
