I mean yes, all of that was unrealistic but now that it’s happened once it just makes it LESS likely that there are still tons of characters left. I think there are 5 unrevealed fighters max and that includes echoes like Ken, but it could even be less than that. I’m certainly no box theory person but if I was to hazard a guess I’d say 4 characters left. Ken, Shadow, Isaac, and maybe Geno or a Pokemon or somebody. I think Banjo is in too but as DLC.
Actually it already happening neither reduces or improves the likelihood. All it states is that it happening again is a possibility now.
It's like raining. You already know it is exists and happened but it raining one day does not alter the likelihood of it raining again in a few months. It just happens regardless.
Like any speculation (characters, dates for Directs, etc), all you can do is look at past behavior to have an idea of the possibilities.
There could even just be one more character. We just don't know. All we can do is guess. So all that can be said is there is up to 5 because it has happened before. But as little as 1 is also considered too.
It's why I never pay heed to "leaks" or box theories etc. It all means nothing at the end of the day as it is still speculation.
I am inclined to say 3-5 myself. I believe the ballot will break most rules of the roster template and the last few are from Ken, Isaac, Shadow, Dixie, Geno, Banjo, Rayman and a Pokemon rep.
I do agree in believing that Banjo is DLC. It worked wonders for introducing Platinum Games and Square Enix to the Smash family. It's perfect for Microsoft.
