Badges have already been said that they all belong to Kalos. It is not the first time that any region has shown more than 8 badges, and badges that don't exist in any game.
Kanto had over 27 gyms, Hoenn has at least 9, Sinnoh was shown to have at least 11 gyms, Unova had at least 14 gyms. The only Anime series that didn't do this was Johto.
