Brazil is fine by me. It is a unique country and you can work with the Mardi Gras culture to provide the pavilion theme (England gets the Cotswolds or Lake District, Canada got the great frosty wilderness towns, France got Paris (winner), Italy got Renaissance city remains, Germany got the Beer Garden treatment, Japan got the Imperial Palace, China the Forbidden City, Mexico the Aztec Empire, and Norway got... imaginary displacement punishment for not providing enough financial support, etc...).
I don't understand the push for Spain. It's a romance language country sandwiched between France and Italy, who are already represented. The country has been fairly irrelevant in the 19th and 20th centuries, let alone now. It seems to me a little more variety would be better. Eastern European, Australasian, even non-Arab African (since Morocco is already there). I get there are issues with Israel, sadly, and Greece doesn't have 2 dimes to rub together to contribute, and Russia, who really should be there but ok, politics (Peter and the Wolf attraction anyone?) all have issues. But that's no excuse to put in another Western European nation.
As for India, there is a lot of play in AK for India. The same could be said for non-Arab Africa, but I would be ok with either reappearing in EPCOT. Spain just puzzles me.
