I've been doing research on Epcot recently and realised that the first time Epcot's transformation was mentioned was at the Destination D event in 2016!
It feels so long as construction began in 2017 for the first phase (Green Mission at Mission: Space, Guardians, Space 220, Skyliner & Remy's Ratatouille Adventure)! Phase 2 became the entrance transformation (removal of Leave of Legacy monoliths), Regal Eagle, and the new films for Canada, France and The Land. We're in the final phase which is the centre with Connections, Creations, Moana and CommuniCore Hall etc.
It's been so long that I often forget that some of the stuff in recent years has been part of the overall Epcot Transformation
