Saw the Verge info. I think its safe to assume its Geno, unless SE really don't want him and rather rep their hugely popular dragon quest series. Either works.
So I know its a bit of a pip dream, but I still like the idea of 13 more coming, 6 newcomers and 7 echos. This would give us 84, which fits in the Smash out or whatever that mode is that only lets you use a character once. I assumed they would want, for the base game, a number divisible by 2, 3, and 4, and 84 is the next one after 72, and I doubt we are only getting 1 more. So my wishlist(with some pretty likely ones) are as follows.
Newcomers:
Shantae(Very high ranking in the ballot it seems, an indie rep with a long nintendo history, Her jammies mode teasing smash like Rodin did for Bayonetta, Wayforward has allowed shantae in a lot of indie crossover games but not a single fighting one most likely due to a exclusivity deal, and Wayforward has been eerily quiet about anything smash, not even liking or responding to comments about it.
Geno(With Vergeben saying this, plus Geno has been wanted for ages, most likely was VERY high on the Ballot, got a mii costume last game, and with other fan requests like Ridley and K Rool in this just seems like a certainty)
Elma(Sakurai is a huge Xenoblade fan, has posted on twitter about buying a mecha toy that looks like her mech and has shown in the past to use toys to help make the characters in smash, Rex and Pyra are just too new and will most likely be DLC due to their designs probably not finished in time)
A pokemon Rep(Either Gardevoir with a Gothitelle echo if that one leak is right, or Incineroar. Gardevoir has not been seen in a pokeball yet and is one of the most popular Gen 3 pokemon, People have been wanting past gens to get repped and a Gardevoir with Gothitelle Echo is a good way to rep gen 3 and 5. Inciniroar is one of the more popular new gen pokemon, has been planned for Ash to get one since the start like with Greninja so the pokemon company could push him, a wrestler type fighter is not in the game yet and could be a great way to get a grappler into this game, which is lacking. If Gardevoir is in I can see Inciniroar being very early or first DLC)
Banjo and Kazooie(Nintendo and Microsoft are very buddy buddy now, Sakurai wanted Banjo for Melee but was worried due to licenseing, Very high fan demand and Sakurai is looking at the Ballot a lot).
EITHER Skull kid OR Hikari and Donbe or any other retro(Skull kid is very popular. Moon is an Assist trophy and no sign of skull kid, Sakurai's chairs could be teasing him(or Shantae same color scheme), is a villain which nintendo seems to be pushing.) (Hikari and Donbe is a personal one I want, a retor character and we haven't seen any true retro characters yet, Did get outfits for Mario Maker, has had music in the game since Brawl)
Echos:
Isabelle-Villager echo(Assist trophy is missing and a new AC AT is in, HUGELY popular, Nintendo pushes her a lot, is the face of animal crossing, could work well as a Villager echo with just subbing out some items for others and maybe adding some new effects to her attacks to make her seem more gentle or accidently fighting at times.
Dixie-Diddy echo(End of K Rool trailer is hinting with Donkey and Diddy trapped and can see an extended one of that being Dixie jumping in to save them, Can easily use all of Diddy's moves, With CHrome we know that Dixie can replace rocket jet pack with her hair twril which works like DOnkey Kongs up B, was planned to be in the last game, highly voted on the ballot.)
Shadow-Sonic Echo(AT is missing and Knuckles is an AT, very easy echo to make, widely popular)
Medusa-Palutena Echo(A female villian and a KI villain rep as this game seems to be putting in more villains, can easily fit Palutena's play style with just changing some effects and using one of Palutena's old custom moves for herself(Heavenly light but dark themed)
Akuma-Ryu Echo(Ken seems to be floating around but a friend of mine made some great points for Akuma. He is the original capcom crossover character with appearing in X-men children of the atom, he has crossed over to Tekken as well, a bunch of ryu's moves in smash Akuma does but not Ken, is a Villain)
Black Shadow-Captain Falcon Echo(No F-zerp reps since N64, Villain, an echo fighter would be the easiest way to fit a new F-Zero character in the game)
Gothitelle IF GARDEVOIR IS IN, or Ninten-Ness Echo(If that 1 rumor is to be believed then Gardevoir would have Gothitelle as an echo, She would rep gen 5 and all but gen 7 would be repped, is supposidly decently popular in japan, can easily be an echo of Gardevoir with silular body type and lots of simular attacks and manerisims.) (Earthbound has not gotten a rep in awhile, and Mother 1 getting an rep would mean each game has 1 rep.)
