Actually he got a lot wrong too.
There's no minecraft content, no 2nd Square rep, Isabelle was unique and not an echo.
He never said she was an Echo either. This is false. What he said was he had no idea if she was unique or an echo. Because his source didn't either.
What he got right was Ken and Incineroar. He never said anything about K. Rool, Inklings, Richter, Chrom, Dark Samus or Daisy. Ridley was already leaked by Resetera and Simon was leaked by Stealth.
And what he got right was all Wii U characters returning(which no, was not an easy guess), Ridley, Incinerorar, Isabelle, Ken, Ice Climbers, Simon, Ice Climbers, Wolf. All characters he name dropped too. Please actually say how it really happened instead of bending the truth. And that's right, nobody leaked those characters to him(Richter, Chrom, Inklings, Dark Samus, Ridley, King K. Rool). He didn't piggyback off of anyone either, but had his own sources. Besides that, nobody actually leaked Inklings. At all. Everybody figured out they were coming if a new Smash game was. They were the only beyond obvious lock that everybody could beyond see coming that there was nobody who needed convincing. No solid arguments for or against in any way either. The only thing debated was why they weren't in Smash 4. At best. For that matter, the leaks started way after Smash Ultimate's reveal, where Inklings had their "trailer"(though only kind of, as they lacked a tagline too, since it was more like a Smash Ultimate teaser than an Inklings Trailer itself). Kind of impossible to leak what was already revealed, you know? But hey, things aren't that black and white anyway.
What you failed to mention is that a bad source tried to leak that there were no DK characters. He didn't believe the source either. This is information he was never going to mention since he only leaks information he believes to be true. But another user decided to release that PM to discredit Verge. The information Verge actually got was likely based upon the demo. Besides, you also didn't even mention Pokemon Trainer's return. And even then, what Verge actually said was certain characters would be leaked at e3, not simply "in the game". Ridley, Wolf, Ice Climbers, Snake. And that at some point Simon will be showed off, not necessarily then. Ridley was a very difficult guess on its own, and most were not banking on Snake. IC and Wolf aren't too hard to guess since they were expected. Stealth also was proven to know next to nothing these days, with barely a track record at all(compared to Verge getting almost the entire base roster correct, due to the actual information he had, and how it was presented). Wasn't ResetEra also the one that thought the Grinch leak was real?(I can't remember that one) Never mind it was particular people in ResetEra that knew of Ridley, not the whole place. One person leaked him. They aren't a hive mind. That's not how it works.
He said all the Wii U characters were returning alongside Snake and Icies, but that's only a half truth, as that's vastly different information to EVERYONE returning.
Even Nintendo employees were literally surprised at this.
Almost nobody knew. At least know the whole situation and why it was never leaked. That's not how leaks works. Nobody ever gets the full story from the start. Even Smash 4's information was split up to some degree originally. Gematsu didn't have the full details either. The fact we got a full picture leak of 4's final roster was a fluke, nowhere near something that is reasonable to expect. Even the leaker himself(one who is two people who dealt with the leak) made that clear. Any leak about a game comes from multiple sources. The whole "everyone is here" was an extremely well-kept secret to the point that a ton of people at Nintendo were kept in the dark. Verge can't leak the impossible if his source would never know, which is an accurate assessment of the situation. If he had said "only these characters and returning and nobody else", you might have a remote point. But you don't. He didn't literally say a certain characters were not in, which is an actual proper statement. You either know something or you don't. He, like most people, didn't know the entire roster was returning. Simple as that. Life isn't that black and white as you're attempting to make it, and never will be. Leakers get information from more than one source. This means not only can some sources be right, and some be wrong, but it means that some sources won't have the whole story. Verge clearly didn't get the whole story, but bare two things, got the rest right with the information he actually released. Coupled with leakbait, and it's easy to see why the Minecraft and SE content wasn't main game. Could also be last minute changes to plans, or just "talks about consideration of the ideas". His sources even were conflicted on how MC was going to be in. Good reason for that. And the fun part about the SE rep is he had multiple different possibilities. He also found out enough information to declare it "it might be base roster or DLC". Now, he did jump the gun too early on the SE information, absolutely. So see my next paragraph, cause the MC and SE stuff should be held against him. He actually got that wrong entirely. Not stuff he gets wrong if you stretch it enough to make him look bad when he told the truth.
Reality is all he got wrong was Minecraft content and SE content. That was it. Since that's how leaks work too. Not knowing a character is meaningless in itself. Saying a character isn't in is an actual big deal. If he didn't get leaked a character, then he couldn't "get it wrong". If he says a character isn't in, but the character is there, then he would be getting it wrong. But that's not what happened at all. Did he say, for instance, Pichu wasn't returning? That we'd get no new DK characters? That Dark Samus
wasn't coming? No. Those would be legit knocks against him. There are two things he said were coming and didn't happen in the base game. That's all he actually got wrong. He got way more right than you realize, especially since you clearly didn't know that the Isabelle thing was mistook as people hearing he only heard and said she was an Echo(which wasn't true either. He nor anyone knew her status and said literally just that).
