A lot did get announced in 2019 for Epcot like Play Pavilion, Mary Poppins and Journey of Water but the pan happened causing most of it to be cancelled. 2020 was the announcement of Tiana's Bayou Adventure
Also, most of things opening now where announced pre-2020 like Zootopia Land, World of Frozen at HKDL & WDS, Fantasy Springs at TKDL.
In fact, the most recent announcement was Tiana's Bayou Adventure in 2020, the Toontown Revamp in 2021, and San Fransokyo Square & Avengers Multiverse Attraction in 2022. I think it's safe to say all the parks worldwide could do with some announcement about what is coming post-2024.
