I am really starting to think this is all a trap. If this guy way back when you whip up that Palutena leak, imagine what could be achieved given the time, Brawl hacks and enough of an inclination.
It seems pretty much unthinkable, but we've not seen renders for a few of these mentioned characters (notably Ridley), and the only ones we've seen in game are Bowser Jr, Lucina and Shulk. If this guy has the talent to make that Palutena render, given the chance for the whole "long game" on such a leak it's entirely feasible that he could have put together a working Bowser Jr, a polished Lucina and Shulk and been "leaking" similar leaks for a while to get a story out there to "confirm" with information he's started spreading around.
Throw in the obvious attempts at trolling with the whole DLC thing, the "errors on purpose" that have apparently been done if some are to be believed, and the Palutena render and it seems highly suspicious. Why would someone who would have access to Nintendo's ESRB video (if that's what was sent) be so damn talented as to be able to make the Palutena render.
I don't know, maybe they're seperate people and this has all been mixed up, but if they are that ridiculously talented and keen on messing with people, it's not beyond the realms of possibility here.
I think we should keep Ridley's fireworks display safely away in the cupboard until we've got some more information still. It seems too much to be faked, but we don't want Ridley's "confirmation" (the weakest of all these leaks to be honest) to go the way of Chrom's.
