Could be. They have shown all stages, so any new character would have to be from a franchise already represented in the game. Sonic is, so maybe it could happen.

There has not been any confirmation all stages have been shown. I'd be shocked if we were only getting 5 new stages total, so I highly doubt it. 

They said there are 103 stages in the game and they showed the selection screen with 103 stages. Maybe they could add more, but it would be weird to brag about there being 103 stages if there are more.
