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

[Turkish]

They're in denial. Mario Kart is a much bigger franchise than Smash Bros, it is far less of a system seller. The effect of MK wasn't that big. You will see, Smash Bros will sell millions, but it will barely sell any Wii U consoles. Most people who want Smash already have a Wii U.
