I must say that I don't personally like how everbody is speculating on what the new region is supposedly based on (though as a moderator I'm fine with the discussion staying here). For one, people seem to expect carbon copies, that the region will be just as much Spain/Italy/England/Hawaii as Kalos was France. I rather think it will borrow some elements, but they're not required to carbon-copy all the geographic features. They would probably pick fire truck colours and vehicle license plates to suit the pallette of the surroundings, rather than basing them on what is used in the country the region is inspired by. Nor do they have to make Poké-Italy or Poké-England just because it's supposedly next to Poké-France. People are strangely confident in their predictions, or believing rumours I can pretty much guarantee to be baseless, even though we've been told practically nothing. We've seen once scene, that's all. A still image to boot, if I'm not mistaken. Let's not jump to conclusions based on so little evidence.
Then I visited the Bulbagarden and Serebii forums and saw what everybody over there were extrapolating and the conclusions they were jumping too, and came to realize you guys here at Smogon are pretty reserved and restrained. There are ten-page threads of starter speculation, based on absolutely nothing whatsoever, and similar-sized ones about Legendaries speculation, and let's not get started on the wishlist threads. Well done everybody here, by comparison!
