With regard to project timing, 2021 is more likely considering a fence just went up, but the major Orlando resorts will likely always be in a constant state of change in some capacity. Right now, Universal has Harry Potter, this ride, Fantastic Worlds, endless summer resort hotel, and maybe another project that I'm forgetting about. Disney itself has Tron at Magic Kingdom, Galaxy's Edge at Hollywood Studios, Ratatouille and Guardians of the Galaxy at Epcot, various upgrades and changes at Disney Springs, the Skyliner cable car, and eventually (not quite yet) monorail upgrades. The heavyweights are battling it out and on paper it looks like Disney has the edge - I'd argue that Universal can't build this ride (and Fantastic Worlds) quickly enough.
