Looks like a scaled back version of the Galaxy's Edge the two US parks are getting... maybe containing just the Millennium Falcon attraction (or something new altogether?). Arendalle looks to be taken straight from what was planned for Disney Sea (which I had the feeling had been canceled). Marvel certainly seems interesting as most of the buildings you see in that concept are already there. I mean, you repurpose/retheme the resturants/shops and they already talked about the Rock n' Roller Coaster retheme, but t looks at most only one new attraction here (in the top center behind the jet/aircraft). Given the long/skinny nature of the building, maybe a port/retheme of the Iron Man ride they added at Hong Kong?
Either way, some much needed investment to this park! (though I have to wonder how much this has an impact on the scope of the EPCOT overhaul)...
