Yeah most of Verge's stuff or any leak from THAT long ago hasn't been true or has been confirmed a hoax (like the star fox grand prix thing). I wouldn't bet on something he or any leaker said that long ago, things never leak with such a huge gap of time between being confirmed, we know most of the things that have gotten confirmed so far never took anywhere this long. Leakers just wont admit when they bite leakbait, lol. I still hope we get another SE character regardless, and it could even be the last DLC character, not based on whatever leaker said.
Edit: Apparently Vergeben just came out saying on Gamefaqs that Erdrick is definitely it. But his reason for saying so seems super void and dumb to me. "Me and tansut and other leakers heard it" ? Like seriously? Didn't HIMSELF say that this list is a leakbait situation? To me, everyone hearing a same name only means to me that they are all getting leakbaited equally. It's not denial, I have nothing against Erdrick, I just need better proof than "we all heard it" when there is a confirmed leakbait situation going on behind the scenes, confirmed by vergeben himself in the past. He is relying on piggybacking what others heard despite knowing this could all be leakbait, personally, this isn't real solid proof to me. SE is good at leakbait, so i'm not willing to bite just yet. I need better proof.
