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

[Nem]

Smash will do very well on Wii U.

Why are people thinking it will do well? Cause they are excited to play it.

Why does everything have to be about sales numbers? Sometimes, its about enjoyable games.

There are plenty of differences between the audience of the Wii and Wii U. Nothing on Wii U will sell as much as their equivalent on the Wii unless its a niche game.
