I've got to admit I am a bit concerned about this for two reasons. Firstly, surely it's a bit early to say a solid opening year when vertical construction is yet to start, especially one that's just over (I'd expect a winter opening) 2 years away. As well as the fact that this land looks as though it has more to build than Avatar (albeit far less complex) and they seem to think it'll take almost the same time
Either Star Wars land isn't as indepth as it seems or Disney have finally gotten into gear as I don't know if another delay will be appreciated. That being said I'd personally hold off planning any trips specifically for this based on insiders still claiming this is more likely for mid-2020 and just in case we do end up seeing it taking a bit longer much like New Fantastyland.
