I'll be surprised if Smash didn't do atleast 10 million.
As for Bayo 2 Similar to it's prequel.
Hyrule warriors at 1 mil
Dunno about the rest.

Hyrule Warriors: 0.7 million
Bayonetta 2: 1 million
Just Dance 2015: 0.5 million
Captain Toad Treasure Tracker: 0.7 million

OMG, I can't stop laughing. 

Hyrule Warriors: .0.8 million
Bayonetta 2: 0.9 million
Just Dance 2015: 0.3 million
Captain Toad Treasure Tracker: 1.1 million
And of course Smash Bros for Wii U: 3.4 million

Hyrule Warriors: 1.1M
Bayonetta 2: 1.3M
Just Dance: Who in their right mind buys this?
Captain Toad:1.2M
Super Smash Bros Wii U:7M

Smash WiiU won't sell 4 million though....

Are you aware of the fact that Brawl was on the Wii and that the installed base of the Wii is a little bit bigger than the Wii U?

I am completely aware of that but an install base can always grow and smash bros. is a really big game. The Wii's install base was kind of misleading because an overwhelming majority of those owners were casual gamers that didn't even bother with the smash bros series. So it's not totally unlikely that in its entire lifetime that smash will sell 12.24 million+ Though in hindsight I realize I spoke too soon and my prediction is really big but it's not inconceivable and I think at least it could reach 8 million lifetime. I mean, look at melee, it was released like a month within the gamecube's release and the gamecube's install base at the time was worse than what the wii u is right now and it's lifetime sales are 7.07 mil with a system that only sold 21.74 mil lifetime.

Nope, no, definitely not. Just ignore my insanely optimistic and naive opinion please, thank you

Hyrule Warriors: .1 million
Bayonetta 2: 1.9 million
Just Dance 2015: 0.4 million
Captain Toad Treasure Tracker: 0.8 million
