People who think Vergeben isn't legit just because he didn't leak everything down to the exact detail don't understand how these leakers gain their information, or even how their sources do, if his leak was as incredibly detailed as a lot of those fake ones are he'd literally be a god tier leaker, stuff like that just doesn't happen. It's all fourth, fifth or sixth hand information, it's very likely that Vergeben's source doesn't even know the guy who's actually the source of it all, or that the source of Vergeben's source even knows who's leaking this stuff, furthermore the original source of these leaks, however far he might be down the line, has very likely only seen bits and pieces from the game, or maybe only even have heard about them, that's how far out legitimate leaks tend to be.
Vergeben gets a lot of stuff wrong, so I'm not inclined to believe everything he ever says, but I have absolutely no reason not to believe his initial Smash leak, which included Simon, and only all the reason in the world to do so. We also have to take into account that this is a guy who's leaked a lot of stuff correctly outside of Smash too, and although his record is very patchy you don't just guess your way to becoming a semi-credible leaker, the much more logical explanation is that he simply has a very mixed bag of sources.
The things he got right were no coincidence, and selling his Ridley prediction short is absolutely crazy, saying anything other than Ridley being considered almost impossible by the Smash community is just revisionism. It's not even that I desperately want his leak to be real, I already got what I wanted out of it, and before then I was far more cautious about it, but I do think that he deserves a bit of due credit for actually getting his stuff right.
