Mentions a legendary with a wheel (yeah it says “past/future dog” but it’s close enough to be mistaken from MiraiDON and KoraiDON even in the Japanese translation.

Mentions tomes replacing badges and there has been a lot of tome imagery (books close at the end of the trailer showing cover art).

We will see when the region name is revealed if this is real or not.

+1 points for not even mentioning the starters, +1 point for an obvious gamefreak move (not one but 2 new charizard forms)
