A few hours ago, a new sign was installed in front of the Captain EO attraction at Epcot. In addition to the attraction's logo (and an artwork representing some of the main characters seen during the 3D show), a new message now invites Guests to "see them change the world one last time," as the "farewell mission" of this ragtag band will take place on December 6, 2015. The attraction will officially close its doors to Epcot Guests on Monday, December 7, 2015.
The official Disney Parks Blog confirmed that a new experience will replace Captain EO next month:
"Today, we’re happy to share that coming in December, Epcot guests can experience beloved Disney and Pixar animated shorts in a new 4D experience located in Magic Eye Theater in the Imagination Pavilion. “Disney & Pixar Short Film Festival” will include a look into the visionary minds behind some of the world’s most iconic animated films today.
Then inside the theater, guests can put on their 3D glasses and enter the imaginative worlds of three animated shorts, which will burst to life on the big screen (and in the theater) like never before."
