Don't bring that argument up here. I'll just say that all things that they have said and done with JUST Sun and Moon is indicating a new generation, however
Pretty sure he's a guy who would say that. There's too much room for doubt with how everything else is going.
The two avaliable slots for pentagons after OR/AS is a thing that, as far as I know, he and some other guys discovered. Lots of people write it off as not meaning anything when it comes to gens, but pretty sure he can explain otherwise.
I also guess that he doesn't believe the Zygarde moves are to be distribution moves, like actually scrapped, because we've had this exact case with 5th gen.
That is really all, please don't delve further here. Go to /vp/ or something, but you'll be stoned to death for having such a skeptic viewpoint of the situation.
