Like you mention, Banjo got whatever. He didn't get costumes from the Banjo series and he didn't get Microsoft costume.
We're trying to figure out a pattern but it's entirely possible that there isn't a pattern. For all we know they could release a bunch of Mii Costumes without it being tied to a fighter. Remember Smash Bros 4?
They could do whatever they want however they want.
But how likely is it? How likely is it that Sakurai would decide to put in a bunch of costumes from SquareEnix, and release them all at the same time on some random day? Four ****ing costumes, released on casual friday, completely contrary to how he's released costumes thus far? Just because something's possible doesn't mean it's likely. Just because the Mii costumes list can be faked, doesn't necessarily mean it was faked.
I'm honestly getting so sick and tired of you using the same goddamn argument to shut down every point people make in support of this post's legitimacy:
This guy who got some things right made a post with a list of Mii Fighter costumes.
"Yeah, but it's possible to fake it."
But he got half of the Mii Fighter costumes he listed correct.
"Yeah, but the rest of them could still be faked."
But if this is legit, it could mean Geno's coming!
"Yeah, but maybe he didn't mention Geno's costume just to troll us."
Why would he do that if he only intended to show this list to a grand total of 3-5 people? It's kind of an inefficient troll. Plus, why would he purposefully tank his own credibility just to spite Genobros?
"Well it's possible."
But if Geno's costume is coming back, that would make 4 SquareEnix costumes! How would they be released?
"Sakurai can release them whenever."
But it would go against how costumes have been released up to now. Why would he do that?
"Well he could."
Again, don't get the wrong idea, I don't mind you not believing the leak and expressing your doubts. I'm just getting sick of hearing the exact same nothing argument from you.
