As of now, only Guardians and the Dining: Space are fully approved. Communicrossroads is practically greenlit, but in design purgatory. The only other pavillion that could have a change by 2021 (barring a last minute "IP-rovement" based on something kewl and fresh at Imagination or Seas) would be the Land. As for Spaceship, Seas, and Imagination, they will each get their reno in due time (pre-2030, post-2021, and in the order listed). Also, unless Guardians takes-off in more ways than are on the blueprints and price tag, Festival Center will live on.
