I don't really care much about the order in which they reveal characters, but Dixie would make some sense if they're including her.
As for characters I want eventually, Little Mac would be awesome. They'd have to come up with something interesting for his moveset, because I feel like his own game naturally limits it to regular boxing moves. But as long as he can duck and weave and hit 'em with his star punch, he'll be a blast.
I'd love Xenoblade to get a representative, and I think Shulk is a likely bet for inclusion. Honestly, though, I feel we have enough sword users as it is, and I think (Xenoblade spoilers) Mecha-Fiora has more potential for a unique and exciting moveset.
For the same reason, although I wouldn't mind Magnus or Palutena, I suppose I'd prefer Palutena. She's a boss in Uprising, so they can draw her moveset from her attacks in that fight.
