Masdar City in Abu Dhabi is probably the closest modern equivalent to Epcot’s original vision, though it's debatable how much of the master plan will actually be built. Songdo (near Seoul) is less sci-fi-ish but much farther along in development. As an aside, Niemeyer's buildings in Brasilia - particularly the cathedral and the palace - are phenomenal pieces of civc architecture.
