So, I am beginning to get kind of worried about Wolf now. I don't see the point in leaving him out, especially with Lucas and Roy here, and a new Star Fox on the horizon. I also don't see the point in bringing back two Melee vets, but only one Brawl vet, considering that, aside from Mewtwo, the Brawl cuts were much more painful. Obviously, we don't know what's planned, except that we will get at least two more characters, but I like to think that they wouldn't have given us three characters at the same time if there weren't more coming before the ballot, and would have spaced out the releases of Roy and Ryu if we weren't getting anyone in August. I also feel like, if we weren't getting anymore vets, Sakurai might have said so after Lucas and Roy, so fans of other cut characters wouldn't get their hopes up.
I feel that, if we do get more vets, than Wolf would be at the top of the list, but I just don't know. Wolf feels like a legitimate hole in the roster to me, upon release of the game, not having him OR Mewtwo was a major blow.
On the upside, I think that Mewtwo, Roy, Lucas, and Wolf were probably planned for the initial game, but were cut due to low priority. Lucas and Wolf had assets in Smash 4, leading me to believe they were at least worked on. If that was the case, the characters that were cut from the initial roster would probably be top priority, hence why Mewtwo, Lucas, and Roy are three of the first four characters released.
But I hate not knowing, it's the worst part.
