Honestly I think that Geno has a 50-50 chance to get in. His best opportunity was for base roster or early bonus DLC (replacing Piranha Plant) where Sakurai chosed the fighters. Its a shamed that he had limited resources, if not, Geno would probably have been included in Ultimate.
And remember, we don’t know which criteria used Nintendo staff to choose DLC fighters. As I’ve said before, we don’t know if NOJ let NOA or NOE to participate in the selection. Its also been said that some companies have approached Nintendo to get their staff in Smash (like Ubisoft or Bethesda). Its likely that SNK offered Nintendo content of their IPs in Smash, and thats how we got Terry.
As for Sora, he is also very requested, and it’s rumored that he was the real winner of 2015 ballot but Nintendo couldn’t make an agreement. Although that was 5 years ago, and Nintendo has changed their staff, so maybe they want to try again. Who knows.
