12. No countries have been added since 1988.
When EPCOT opened to the public on October 1, 1982, there were only 9 countries represented on the World Showcase. The Morocco pavilion was added two years later in 1984, and the Norway pavilion was added in 1988. Though there has been talk over the years of new countries being added, there have been no additions to the World Showcase since 1988 when Norway made its debut at EPCOT.
