Wait, wait, wait, where did Sakurai he wouldn't refer to the ballot for another game?
I mean, the ballot was noted it would be potentially used for future games, not just one.
That said, Geno being 3rd party and not relevant is always going to hurt his chances. Sakurai doesn't just get a character automatically if he wants them. It's never been that simple. He even noted he failed to get Snake back during Smash 4(the context of the interview isn't clear if he attempted to get him back during base, DLC, or both, mind you).
