With multiple sources now confirming, it seems likely that Brazil is the new country being added to World Showcase during the multi-year expansion and re-imagining of Walt Disney World’s Epcot.
The pavilion is rumored to be going between the Italy and Germany pavilions in World Showcase, an empty 1.5 acre plot left for a future pavilion since the park opened in 1982. The pavilion will likely include an attraction, but there are nor rumblings as to what it might be at this time.
Brazil will likely be announced for Epcot at the D23 Expo 2017 during the presentation on Walt Disney Parks and Resorts. This rumor dates back to a 2011 story run here on WDWNT.com.
