OK, guys, I think it's time to put this Geno/Sora argument to bed. Here are the facts:
1) A character can get into Smash with or without a history of their franchise being on a Nintendo system
2) There is, however, an overwhelmingly higher percentage of characters in Smash that DO have a history with Nintendo, hence there is a statistically higher chance of such characters getting in due to a higher bias from Nintendo itself
3) Both Geno and Sora are highly requested by fans, however, this being a GENO THREAD means that Sora should be discussed in the context of Geno speculation and not a straight-up campaign plug.
4) Objectively speaking, Geno would require less red tape to include in smash due to
A) Him being owned by only one company instead of the complex combination of Disney and SE (Nomura)
B) Rights to his inclusion have already technically been established as evidenced by previous content (Spirit and Mii costume)
C) Him existing as a Mario spin-off character
D) Him not belonging to a predominantly Playstation exclusive franchise
In short, COULD Sora happen? Absolutely. WILL Sora happen? We don't know. We just don't. Is there currently any evidence, leaks, official commentary, etc. hinting toward Sora? None that I know of. As for Geno, what do we KNOW?
1) Sakurai has personally said that Geno "would fit great in Smash" and that he had "wanted to add him since Brawl".
2) Geno not only had a Mii costume, but it was also the only one to have a splash screen and is currently (and suspiciously) MIA.
3) We have at least two leaks (Mii costume and Cacomallow) that not only point towards Geno, but at very least have skyrocketed his visibility among devs and Smash fans alike
4) The two largest franchises owned by SE are now represented in Smash Bros, alleviating what should be the most staunch reason for hold-out on the part of SE to include a character that doesn't pertain to either.
Now then, let's move past the semantics and accept the fact that things are looking pretty good for our star boy right now.
