For anyone who wants to wait until Universal actually comes out and issues a press release that 100% confirms the attraction in a public fashion should be aware that this company very rarely operates like this nowadays.
A great quote I've always heard was that "Disney is announcing things way before building them and Universal is building things way before announcing them."
That's kind of the way things are. Kong looked like Skull Island in construction so far along before the PR that the president of Comcast, forgetting that they still hadn't announced it, accidentally name dropped the ride in an earnings call! And yes: at the time Universal Orlando even refused to acknowledge they were even building a King Kong ride! The project was referred to officially as "expansion" in front of guests... that's it. Sometimes just "what? What's over there? I don't see anything over there".
My point here is that IU holds their reputation very dear, and I would 100% trust them on this one. Waiting for Universal themselves is going to be a long wait, so I would sit back and enjoy the PR tap dance til they finally confirm, "Yeah ok we're doing something here."
Unless it gets leaked to the LA Times again...
