I'm just going to avoid DLC choices altogether, that gets way too controversial if it's not a popular newcomer, though at the minimum, I'm just going to keep every cut veteran.
Meh that was a given. But I still believe that a historical retro will still happen, and Jumpman is the only notable one right now.
I only put Kawashima again only because I think he might relook at the idea again when a new Brain Age game comes out (which is pretty likely to happen given it's massive success) and finds out he's feasible for combat with his addition of hands in the newest game.
I believe there will be some popular and some unpopular requests getting in, a balance between that. Isabelle, Tom Nook, potentially Ganon (given his "villain" appeal), the new FE protagonist and Xenoblade protagonist that people will bandwagon (Like Chrom), Takamaru (Who people will likely support if there's no retro character in sight that has gotten a new successful game), Chorus Kids (If they aren't implemented as Smash DLC, will likely gain a spike in popularity again mainly for being planned and being unique), I'd say there's enough potentially popular candidates in the base roster already, the only few potentially unpopular ones are Jumpman and Dr. Kawashima.
You gotta think hypothetically and not just take Smash 4 ballot popularity into account. :L
No third party newcomers on the base roster. Ryu will probably stay around.
Not too sure how likely that Ryu will stay to be honest. :/
Another FE character from a game that will be pretty darn old by the time the next smash roles around.
Adding Cross when the series has two games and if they do get more, why not just add the most recent guy?
Like I said, those are only temporary, I will likely change when the next game is announced in the next few years or so.
Three AC characters? Now I wouldn't mind one more next time, but two?
Given the giant fanbase Isabelle has gotten, she'd probably be one of the biggest requests by the time SSB5 begins in development. And the popularity Tom Nook has gotten (even when he got deconfirmed) will likely spike again in SSB5. Both have pretty interesting characteristics to make a moveset from to get in the base game too. (Using merchant tools for battle and potentially Raccoon Mario skills, Isabelle having her moveset based on the "mayor factor" of Animal Crossing; Villager's moves are mainly based on the usual AC activities, while her moves could involve public work projects and more.)
((Taken from the deconfirmed group's Isabelle support thread))
Doc stayed but Lucas and Wolf didn't? There's no reason to keep Wolf out anymore.
If time constraints are on the line, Wolf and Lucas would likely be low priority,
especially Lucas since Itoi stated that he would not make a new Mother game, and there are likely newcomers from new games who would receive priority over these guys. If Star Fox consistently gets new games with Wolf appearing, I could see him have a good chance of returning, but I still see him in the middle bottom priority somewhere still.
Clones? Young Link, Pichu, Roy, Lucas, Wolf, Dark Pit AAAND Lucina.
Clones who would likely get brought back if time constraints gets the best of them and to get people's mains back)
Continuing King K. Rool and Isaac being out is odd considering the power that they are pulling in the Ballot as is.
If King K. Rool and Isaac appear in new successful games, then I might add them to my roster, as of now, that hasn't happened yet.
