>China. Focus on Hong Kong or Beijing and have landmarks like the great wall. Pokemon has been proud to promote how they're translating games into Chinese now, so this is probably the most likely next step
>West coast of the US - Seattle down to LA. We've had the only notable part of the east coast with Unova, then Hawaii, now could be Vegas and Hollywood's turn
>Australia has a decent identity that would be good for a setting. It might be a little too similar to the recent British culture, so it might have to come later
>Mexico is a popular vacation spot and also have a very tangible identity for a setting. And the culture and climate are quite different to the UK, so it'd be a nice next step after Galar
>Brazil and Japan have always been pretty close. I could see this happening eventually, but probably not next
>Somewhere in Canada could be a region some day, but not after the cold-ish region of Galar. It would have to followup a warmer region.
As for Africa, east Europe, and Western Asia, or any of the Pacific island countries. No. There's some great cultural inspirations around the world, but if your country isn't buying pokemon games or pokemon games aren't being marketed to your corner of the world, you're not getting a region.
