Feels to me that instead of having both something in October and November, like we expected, we might just have one presentation left, as he's talking specifically about the pacing of the reveals. I'd guess either in late October or early November we'll get a Smash Direct that gives us a huge blowout of information, it could potentially reveal as many things as the final roster, Spirits, Online, All-Star, Stadium, and the rest of the game's smaller unknown quirks, which would probably be able to stretch to 30 minutes worth of runtime.
It does of course indicate that we don't have many newcomers left too, so I'm feeling that Vergeben's characters are probably it. It could still be slightly more, but I'm perfectly fine either way as I got what I wanted long ago, so I'll keep my expectations on the lower end. If it's the case that we only have those three left then I'll feel even more lucky that the ones I wanted were able to make it, being a newcomer in this game is quite the privilege with the limited amount of spots.
