I thought Stealth leaked Snake? Either way, It's not a stretch to think two leakers got the same info.
I'm not saying Verge is 100% legit (as I stated in my last post about him, I think the Pokemon stuff is a little silly) but I will say he has gotten some things right, and he has just as much supposed credibility as any other leaker like Loz, Stealth, or even Emily Rogers. They get stuff right, and they get stuff wrong; no leaker is 100% correct unless the leaker is straight from people involved with the game, such as 3DS' ESRB leak.
All in all, it's good to be skeptical of these things, as the odds of these leakers being 100% correct with zero incorrect guesses is very slim unless their source goes deep in the dev team and is intentionally leaked by Nintendo themselves for marketing. Just my opinion, though.
