I find it interesting that people instantly believe Vergeben about Incineroar and Ken because that confirms Box Theory, but then he brings up the SE character and instantly the conversion turns to "Well, they're obviously DLC!"
...Why do we assume 100% they're DLC? And if we're willing to be skeptical and say that part of Verge's stuff is wrong, why are we adamant that Incineroar and Ken just can't be wrong? There's word twisting and excuses going on both sides, I think. People are saying this is ESRB all over again. Here's the thing; ESRB had proof. Like, actual, proof, with screenshots, videos, and people coming out and confirming "Yes, this is real" and there was no way to disprove it. Equating this theory to Gematsu would be more accurate IMO, as Verge and Gematsu are both text leaks that got a lot right. ...But Gematsu failed in the end, due to outdated info and misinformation. There is still a very real possibility that can happen with Verge. Again, I feel the people who are trying to both prove and disprove are cherry picking information without being mindful of the same song and dance we did back with Smash Wii U.
Another interesting point: Verge only came out and doubled down on Incineroar after the Box Theory started gaining traction. I'm not accusing him of lying, but to say it's impossible without proof is a bit odd to me. We have to take him for his word. He claims he has multiple sources, but how do we know if this is true? None of us know him, none of us know his sources. It is literally impossible to know what is and isn't going on with Vergeben right now, so IMO, our best course of action is to wait, and if people wanna speculate outside the box, just let them. Seriously, what does it hurt? Why do we need to shove this theory down everyone's throat and say "You can't say that, it goes against the box!" People enjoy speculating, it helps make the wait for the game easier for some, and it's fun to support your favorite characters and come up with a moveset for them.
