I don't know what you people are worried about
We've got up to 5 more roster slots that aren't filled out, and we have a leak posted almost a month ago that predicted everything in the current leak, in addition to Ridley being a character.
Far as I'm concerned, Ridley's playable, and I am very happy with that.
Remember than gematsu happened, I'm of th eopinion that gematsu was based on leaked info, but something went wrong in the process, I don't think we have solid evidence for now, neither confirmation non diconfirmation (and thats in a quite better shape than Krool thread or Isaac thread for example)
Points in favor, the original leaker said Ridley will be playable, and so far i say we can confirm that the original leaker HAD genuine info, everything regarding bowser jr and shulk is bullseye with the leaked video
Sadly that is still not solid proof. I think that if Ridley was featured on that ESRB video that the leaker clearly saw, we would know by now, that doesn't mean that the ESRB video showed everything neither, in fact some people say that all star mode was locked and therefore there were still characters to unlock. So yay for speculation. were the original leaker got his information on Ridley if is nt the video? did it came with a document? still a lot unknown.
Here I'm hoping for Ridley and mewtwo, Wolf, Snake and IC DLC to happen (if they are cut) and ganondorf to have a new neutral b. with this the roster would be perfect IMO
