While I still believe this leak to be fake based on all of the reasons I gave before (and the point about the font, I didn't really analyse the fonts beforehand), I find this image pretty amusing:
Also yeah, I think people predicting cuts should really stop at this point. It was stated in a very early interview that nobody was planned to be cut. They don't aim to cut any characters from Brawl.
With that in mind, it was also stated that the roster would not be expanded as much as it was in Brawl (a lot of people took this as "it will be smaller than Brawl"). Essentially, we're getting less newcomers.
So if anything, cutting characters seems like something they would really want to avoid this time around. Splitting up transformation characters also has the side effect of making the roster look bigger than it otherwise would.
Snake is literally the only newcomer I understand people being doubtful about, but even he still has a shot at this point.
