Changed my mind on some things after hearing about when Sakurai knew what the roster was gonna be
I think we will get 9 real characters and 3 echos.
Newcomers
Inkling
Ridley
Elma (mech character from Sakurai tweet, fits with timeline for roster being finished)
Simon (matches with rumor, snake/Bomberman shows better ties with Konami)
Chorus Kids (some things suggest these suckers were being worked on for smash 4, fits Sakurai weird character, gives rhythm heaven a rep, I think rhythm heaven had a release around time of final roster being figured out)
Decidueye (most popular among the new gen starters, Pokemon will def have a new rep, probably a greninja situation)
Geno (had a strong cult following, better relations to square with cloud, Sakurai has talked about his inclusion/fan desires, mii hat)
King K Rool (iconic to older Nintendo fans, probably did very well on the poll, has been very popular for awhile, mii hat)
Banjo Kazooie (big 3rd party character/potentially with Minecraft stage deal, iconic to older Nintendo fans, Phil spencer open to it, Probably did well on the poll, was in line to be potentially in melee)
Echoes
Daisy
Isabella (popular probably did well on the polls, not much to go with moveset wise but would be very easy to work with villagers moveset)
Chrom (fans were teased a bit with last game, he was very popular then, easy with Ike, Sakurai doesn’t like to hurt fans)
Dlc I think it could be from 6-9 characters
Dixie Kong (easy semi clone, probably did well on ballot, was going to be included in brawl, has appeared in new titles)
Isaac (golden sun has no rep, assist trophy is gone, probably did pretty well on polls, has been requested for awhile)
Paper Mario (probably did well on polls, has had an entry not too long ago, has a stage)
Rayman (Ubisoft wanted him in, Nintendo’s relations with Ubisoft is strong)
Spring Man (main character of brand new title arms, would be base game of roster hadn’t been already realized)
Heihachi (Bandai Namco will probably get a second rep due to very good relations, Harada wanted him in if I recall, could be another fighting game character to add to the roster)
Shadow ( easy semi clone, no assist trophy so far, I imagine he did very well on the polls, Sonics a popular enough franchise for a 3rd party to receive another rep)
Crash Bandicoot (just got the trilogy on switch, may have done well on poll, iconic rival to old Nintendo)
Spyro (may get its trilogy on switch, only coming if in a bundle with crash since Spyro is iconic for the time period as well)
