The GF staff were researching caves or some shit in France, which is next to Spain - So the next games could have a connection Kalos
The Tapu's designs on their body seem to match past region/real world things.
Tapu Koko - Native Indian head dress - USA
Tapu Lele - Bikini Top, Hula skirt - Hawaii
Tapu Fini - Kimono - Japan
Tapu Bulu - Nose ring, Sombero (when opened up) - Spanish
Madusa was in Spain at some point.
Credible leaks have mentioned the region being based on Spain or Italy (for some reason I think it'll be Italy due to a backpacker trainer in SM/USUM that mentions another region and she has a name with Italian background)
The Oricorios forms are based on:
Cheerleader - USA - Unova
Hawaiian Dancer - Hawaiian - Alola
Fan Dancer - Japanese - Gen 1-4
Baile - Spainish - ???
So they all feature something connected to past regions and what they're based on.
There's prob more but it's all I can think over in my hungover state.
