I really don't see Snake returning. Toon Link was surprising, definitely, but with the release of A Link between worlds, it kinda made sense at the same time.
I really hope that if the roster doesn't really get bigger, they'll drop at least 5 characters. I want as many new characters as possible
I never have a favorite character. Sure I'm better with some than with others, but I often I don't quit the game till I used all characters :3
Also I really hope Jigglepuff gets at least one new move. Same for Toon Link, otherwise I'm really disappointed in Toon Link and wouldn't want him to return...
Hmmm that Ike theory seems legit as well. Oh well I don't really care. I just want many new characters and íf old ones are returning I want them to have as many new moves as possible :3
