Hmm, I don't trust Gamefaqs for shit but we'll see if any of his other predictions pan out.
I remember like, way way way back during the Brawl hype train when I was a wee kid on GameFAQs and I didn't know any better, someone leaked Ness in Smash Bros. and Porky as a boss in an incredible descriptive way, right down to "Lucas trips on a vine in the ground and gets his foot caught in it, somehow" (in the leaker's own words in the post)
There's nothing out there about this, I remember it got shot down pretty quickly too and the guy never posted again, but he was 100% spot on in his description. I'd almost think it's something I made up over the years if I hadn't told this story on Twitter before and had a bunch of people say "Yeah, I remember that GameFAQs post too!"
I still wouldn't trust GameFAQs for shit, I just felt like sharing that anecdote. You could totally leak something for Smash Bros. and never get caught or suspected of leaking because there's so much crap out there, who would know? I feel like if I had inside information on Smash Bros. I'd spill the beans on something too just because no one would ever believe me.
