Hm, looking through the thread the only off thing is that he calls the new Skull guys "grunts" and for the new Pokémon he only lists four when there should be five.You can read it HERE, the guy is posting a couple more screenshots in a minute, or so he says.
Why do you say that?
Okay, so which leak mentioned a Battle Frontier? Was that the Chinese leak too?
The 4chan Leaker also posted a bit of the video due to be posted on Friday, that explains the school form of Wishiwashi, you can watch it HERE
