A proposed plan of the WDS expansion seems to be doing the rounds now.
via Disney&More, the details in short..http://disneyandmore.blogspot.com/2018/07/dlp-walt-disney-studios-latest.htmlBacklot
The Tram Tour is staying for now. Potential new station location is near Place de Remy.
A replica of the Cozy Cone Motel (found in Cars Land) is also speculated for this area.Marvel Land (c. 2020/21)
No new occupant for the Armageddon building for now. (It will remain closed).
Marvel Stunt Show replaces Moteurs...Action!Toy Story Playland
Alien Swirling Saucers maybe off, or delayed.Studio Lake (c.2021/22?)
The lake could be the same size as that of TDS, with tiered paths/viewing area similar to DCA.
Potential for some restaurants on the waterfront.Star Wars: Galaxy's Edge (c.2024)
Main and only attraction could be the E-ticket "Battle Escape" (the one where they're constructing the full size AT-ATs in the US parks).Frozenland (c.2022/23)
A E-ticket is planned, but potentially no Sleigh Coaster like HKDL.2024 and beyond..
Land adjascent to the Tram Tour has potential for further expansion. Carsland and Pandora could be in Phase II - or maybe something else entirely.
