D23 Expo 2017
The D23 Expo 2017 in July 2017 gave Disney the opportunity to announce a host of new attractions and changes at the Walt Disney World Resort amongst others.
Many are yet to have firm opening dates but it is expected that most will be in place by October 1, 2021 which is the 50th anniversary of Walt Disney World. Some are happening in the next couple of weeks and there have been several new announcements after D23 ended.
