I mean, at the very least, Verge's 'leak' gives us something to talk about, regardless of it being right or not.
I hate stroking his ego, but it's at least 'something', when the most new information that we've received in 2 entire months since E3 is that Delfino Plaza is coming back, and a couple songs. Other than that though, it's been rehash after rehash.
I know I sound like a broken record, but until actual new stuff starts showing up, we're in the absolute dead zone of speculation, where nothing really matters, and we're effectively sifting through 4chan text leaks to kill time and keep ourselves entertained. At least Verge has 'some' credibly to him, though I wouldn't give him too much.
As for Incenaroar? I mean, Ash is getting one in the anime, this much is pretty much certain, so either this was a happy accident by Sakurai, or it was planned out in advance. Personally, I feel like it was definitely planned out.
The whole "Alolan final forms" getting leaked way before Sun/Moon came out was hella fishy to me, and the fact we saw Ash with Incenaroar on the sketches means that Ash getting one has been planned since before the Sun and Moon anime even began. Would not surprise me if the Pokemon Company nudged Sakurai in Incenaroar's direction to both promote the games, and the anime, ESPECIALLY with how popular Smash made Greninja.
Greninja was already a popular starter, but then he's in Smash as well on top of that, AND he gets used by Ash?
If anything, if Incenaroar is in, he'll be in Greninja's shoes in a sense.
