I think it makes about as much sense as any of those countries if not a little more than some as there is currently no representation of South America. It would, of course, depend what they do with it and all indications were that it would have just been retail and dining, which is disappointing and doesn't add that much to WS. On that note, it would also kind of depend on if they felt a Brazilian restaurant could have made money, and I suspect it is a cuisine that isn't too 'exotic' for the mainstream visitors while possibly attracting the large numbers of Brazilian visitors wanting to see the Epcot take on their home country's cuisine.
That said, I think all those countries could potentially make great pavilions. I don't think we'll see any of them in our lifetimes, though.
