AV, I'll bet that's where the big number comes from. I'm sure you've seen all the models in person. I have to rely on the Imagineering book for looks.
For others, you really oughtta get the Imagineering book if you can. Great photos of models, drawings and works in progress. One concept for World Showcase had it at the present site of TTC. Looked like a big futuristic shopping mall. No exterior theming to the countries, it looks awful.
Another Epcot model shows Future World as two spurs off a central hub and World Showcase with the countries butted up against one another. And, there are many more countries. I'm sure glad the Imagineers opted for the version of WS that we got. I wouldn't mind seeing a country get built at the Outpost and perhaps one in place of MV. But, I'd hate to see one adjacent to Canada. I like the front of the lagoon as it is, you have to walk a bit from FW to get to either Canada or Mexico. It makes for a nice transition.
And scoop, it's not "a possible exception", AK absolutely needs more attractions.
