May I posit a crazy, absolutely insane theory, about this supposed leak, based on what we know for a fact is coming up.
We have two Live events going on in Tokyo (Nov. 3rd-4th), and Kyoto (Nov. 23rd-24th), and it's quite possible that one of the items shown in the leak pertained to a wrap-around banner of some kind for a cylindrical display... Then, maybe this could be what we're seeing:
What if the banner contradicts with various 'Insiders' because the banner shown here is
incomplete? And if incomplete, what if this means this banner is specifically for a display at the upcoming Nov. 3rd-4th Nintendo Live 2018 event? And what if
that means that there is
another banner that is being worked on that differs here, and is perhaps the actual banner the insiders know about, and will be put up for display at the
next event on Nov. 23rd-24th? ERGO...
If the leak banner is inaccurate because it's missing key characters previously leaked from insiders, that means we haven't seen all of the fighters yet.
Maybe.
Or, maybe this is not at all what's going on, and it's only as simple as one side or the other being fed false information, be it by insider or by the leak.
I think the former's more fun, even if absolutely impossible, though.
