I'm seriously wondering just how many Fighter Ballot characters are getting in. We're getting four DLC characters so far, and none of them were voted in by the ballot.
Yet, I really can't imagine the Smash roster going from the 35 from Brawl (39, technically) to more than 60, particularly since Sakurai said at the beginning of Smash 4's development that having a massive roster of characters wasn't the focus of the game. And if we do get that many characters, I seriously hope that unlike our current situation, that 75% of them aren't just ported from an older game in the series.
I want some more newcomer Nintendo(esque) characters on that roster.
