Its because theme park insider put out this

There's a set-up scene outside, and a dramatic drive through the gates to enter the building, but the heart of the ride is the 360 3-D tunnel, as in Hollywood. Plussed-up footage, though.
I am worried that expectations for Kong are wildly exceeding what the ride will deliver. It will be a great attraction, but it's not going to be a 10-minute-plus, Pirates-style ride."
