Sources have indicated to us that a Brazil pavilion will be coming to World Showcase in Epcot. The pavilion would go in the expansion pad between Germany and Italy. This is the spot currently occupied by the miniature train set.
The area is roughly 1.5 acres and houses storage containers. The expansion would include an attraction, but there are no details as to what we can expect at the moment.
We are going to label this as a rumor for now simply because Disney has yet to announce it. Brazil would be part of a “Phase 1” Epcot overhaul and hopefully announced officially at the D23 Expo.
