Current predictions so far, assuming that this is Smash 5 and not a deluxe edition of Smash 4.
Likely to join or return as a fighter
Alm or Celica (or one of the lords of whatever Fire Emblem game is coming next)
Am interested in seeing them join in or return, but I am not counting on that happening:
Paper Mario. Provided he brings his own moveset.
Young Link. If he returns, he better be running a Majora's Mask-themed moveset instead of being a smaller, lighter Link like he was in Melee.
One of the other bounty hunters from the Metroid universe. Probably from either Prime 3 or Prime Hunters.
Who I hope gets cut or demoted from Smash 4:
Lucina -> Marth alt.
Dark Pit -> Pit alt
Dr. Mario -> Mario alt (on the same token, make Nurse Peach a Peach alt) or cut
Toon Link -> Cut, unless the new Link has a different moveset.
Roy -> Cut
Corrin -> Cut. As much as I would like them to get cut, I doubt they are getting cut because anyone from Fire Emblem: Fates seems to get a free pass from IntSys lately.
Bayonetta -> Cut
