Just because that website has three spots doesn't mean that those are the last ones, so don't assume that these are the last three spots, as Sakurai will extend those one of these days. And as for your three characters:

1. It's unlikely that Mewtwo would return.

2. One playable third-party character per company, so there won't be another from that same company.

3. Geno is also unlikely, seeing as we have enough Mario reps.
