It's for sure no easy task. Wii U version would have to squander in abouyt 4.5 million more copies sold. However, Smash Bros continually sells pretty decently at retailers and amazon.com
We can also most likely see a few things that will help it. First, being that there will probably be a bundle for it coming out next holiday, and that will make sales boost very nicely. Second, A price drop for Wii U is predicted this year, and It will probably drop down to 249.99. I know plenty of people in my town that are waiting for a price drop, then they'll get a Wii U. Third, being the general population of Wii U owners will have grown, there for more consumers to buy Smash Bros.
I think it will be hard, but not impossable for Wii U Smash to pass the Game Cube Smash. What do you think?
