This 2014 article shows eight spaces that could accommodate countries and not in a way that would "squeeze" them in or anything like that.

While we have Morocco and Kenya is pretty well represented in AK, I would like a better representation in Epcot considering what a large and diverse continent Africa is. India would be great - food, theming, etc. would be synch. South America in general needs representation at Epcot and I like the idea of doing Brazil with an
Amazon theme. Greece would be great and of course would lend itself to Hercules (a highly underrated Disney film, IMO) and I like the idea of the Caribbean, too - theming would be a piece of cake.
