So updated character count
Now there are 11 newcomers and 25 vets, for a total of 36 characters so far. Brawl had 37 in comparison (39 if you count Pokemon Trainer as 3)
There are now 14 unconfirmed veterans: Wario, Squirtle, Ivysaur, Metaknight, Lucas, Ness, Ice Climbers, Falco, R.O.B., Game & Watch, Ganondorf, Jigglypuff, Wolf, and Snake
If they all made it back then there would be a nice round 50 characters in Smash 4 (although Squirtle, Ivysaur, and Snake are looking unlikely)
There's also Mewtwo, sakurai pls
