A new entertainment venue was announced for Main Street U.S.A. at the 2017 D23 Expo. The venue was to be inspired by the Willis Theater in 1920s Kansas City and promised to bring new entertainment to the park.
However, a report on WDWMagic.com in February 2018 indicated that the project has been cancelled. It is unknown if the project will be built elsewhere or if it has been cancelled entirely. One suggestion was that funds for this project were reallocated to a new fleet of Monorails for Walt Disney World.
The original plan was as follows:
The theater capacity was expected to be roughly 2000 guests with an interior lobby. 1500 guests were expected to have seating in the orchestra level with an additional 500 in the balcony. The expected opening date was by 2021 and the initial show offering was expected to be linked to the 50th Anniversary of Walt Disney World.
The theater's location was expected to be on top of the existing management parking facility between Main Street USA and Tomorrowland with guest access being made off the Main Street USA Bypass.
We are currently classifying this project as "Dead", although the possibility exists that it can be revitalized.
