I don't know why people think Smash will do wonders for the Wii U.

Look at the GameCube. Smash sold more than Mario Kart because more hardcore fans bought the GameCube. The Wii had Mario Kart sell significantly more than Smash, but that had a lot of casuals on it. Wii U now is following the steps of the GameCube attracting the hard core fans of Nintendo, and Smash will definitely get a lot of people on it
