Announcement is different than actual shovels in ground construction. As depending on the project and Disney's need for press they may announce a project 4-6 years ahead of time. So you can't count the start when the announcement is made, but when actual construction starts. Shovels in ground start to finish, the average is 3ish years for construction. Even GE was 3 years, as it started construction in April 2016 and as you said opened in May 2019, so 3 years 1 month.Which new lands are you referring to? Galaxy's Edge was announced in 2015 and opened in 2019. Even then, the headlining attraction wasn't finished and took until 2020.
Avengers Campus was not an entirely new build as Web Slingers reused the existing ITTBAB building and the land is extremely tiny. The E Ticket announced in 2019 only just now broke ground.
