On stuff like this i would prefer no polls so people can explain themselves. Over 15m sounds a bit over the top yet it has the most votes so i would like to hear the reason why people think this.

I see SSB being a Monster Hunter 3 U type deal.

well if its pre installed then no, like how Face Raiders is in every 3ds, that means 35mil sales lol!

Over 15? Not a chance. Wii U would have to do exceptionally well to get near that figure.

If Wii U manages to sell on par with the N64, I can see it pushing past Melee numbers, maybe 8-9m because its a popular series?

Wats yours? (seperately)

no it doesnt.  It is $20/$40 for the full game.  

Who knows. Nintendo IPs aren't doing to crash hot on the Wii U atm.

I dont have an exact number.  Between 4-8m on WiiU.  Maybe 3m on 3DS  Certainly not 15m and i would really like to hear the reasons why people would possibly think it would

EDIT:  3DS is a bit unpredictable as we dont really know how people are going to recieve it compared to the superior console version.  So it may not even do 3m.

I don't think it is, you still have to go to the store and get it. Not sure if that counts anyway.

That's just for more characters as DLC. The actual game is free.
