The length of construction here shows what the current state of theme park design is like. We're looking at a minimum 30 month build here or in other words, this ride is taking longer to build than IOA.
As far as I'm concerned, work has started on the new resort but you're talking about at least a year before any rides can actually be started because of all the foundation work that has to be done first (grading, electrical, plumbing, access roads etc) and if Universal are bringing their A game, expect another 30 months on top of that.
