The S.E.A. story began before D23 with a newly rediscovered artifact in an unopened archive crate. Fans who could not attend the presentation could follow the official Imagineering Instagram account for updates.
A new attraction, Big Thunder Mountain change or Matterhorn connection remains unconfirmed. Those theories remain outside the verified story.
