I voted no, but I'd forgotten that it's releasing on 3DS as well. Sales on both consoles combined should push it past the 10mil mark.

I say yes

10 Million on Wii U + 3DS should be a sure thing.

Yes Smash still hasn't peaked and even if Wii U has a lower install base than Wii it can still outsell just like with the GC and N64 one.

I think 3DS alone will sell way over 10mil, Japan will eat it up which in reality never happen since it was always on a home console. Im gonna guess Wii U will do 5-8mil cuz its not Wii but 3DS version will sell massive maybe around 13-15mil imho

If the 3DS and Wii U games are combined, that is a little disingenuous as to the success of a single game. It would be like combining the sales of New Super Mario Bros. 2 and New Super Mario Bros. U and saying that is how much the latest New Super Mario Bros game sold.
