I had a dream last night that the construction was complete, but everybody was surprised to discover that the addition was not Transformers. Instead, it was a Scooby-Doo dark ride, similar to all the other Sally Dark Rides ones with a few Universal touches (like, at one point, it took a photo of everbody in the six person car and put their heads onto the bodies of Mystery Inc.'s members). The building was themed to a castle, riders shot at targets for points, and the attraction appeared to be on multiple levels.
Of course I don't expect a simple dream to mean that Universal is getting a new Scooby-Doo dark ride instead of Transformers, but I can't deny I wouldn't mind... Scooby-Doo is much more family friendly and would most likely not have a minimum height requirement, unlike Transformers. Universal lacks rides that truly anybody can ride, as you discover when you travel with a 38" nephew.
