It'd have to break about 7m (i.e., beat Double Dash) to not be in the worst 3. I don't see what's wrong with this claim.
Nintendo needs a lot more good multiplayer games on Wii U before it's gonna do that, I think.
Okay I misread that bit but still even saying it is likely it will do under 7m... I just don't know man. Is this what is considered likely these days?
