Is an apple red ofcourse it will, but it won't outsell 3ds, brawl or melee, maybe the original though so top 5 seems impossible. Another fun question will the 3ds version outsell the original smash (5.550.000) before the end of 2014.
And will smash U already be in this list before 2014 ends it has to sell higher than 3.87 million units.
Please excuse my (probally) poor grammar
