In all fairness, that's really only half a land. Besides, Magic Kingdom has Liberty Square and Main Street USA, yet there's still an American pavilion at Epcot. And then there's Tomorrowland, which is pretty much the exact same theme as Epcot's Future World. :shrug:
Personally I think India would be a much better choice than Brazil, at least for the sake of freshness. It as a country really has no similarities to any of the current pavilions.
