I would guess longer since they have to build a whole new setting and temple/jungle queue, the restaurant would have to be completely rebuilt and all of the hardscape of the area needs to dramatically change to support the theme of the new area... This is a lot more involved than just a re-dressing of sets and a new theme song...I would put it more at 2.5 to 3 years...from whenever they decide to actually start... The Encanto area could start now since the only thing they would be losing is the Triceratops Spinner...
