I'd be surprised if they don't try to do another October 1 opening like they did with Rat/Harmonious/Enchantment last year for the *Actual* 50th. Although October 1 this year is Epcot's 40th so celebrating something at another park would be weird. If anything opens at Epcot around then It it would be them surprising us and telling us Play is actually happening and gonna open. They certainly aren't in any rush on Moana.No inside into but I bet it’s in previews during September and officially open before Columbus Day weekend.
