PART 5 MAY OR MAY NOT APPEAR
Worlds that are rumored, but may have been scrapped or may not show up.
JURASSIC WORLD
I think the inclusion here will depend on how well the Jurassic World reskin will do in Hollywood, only reason I see it going here instead of in Islands is land use. Think it will come to USO as a ride/land in some form just not here. Only guaranteed ride is the gyroscope dark ride, maybe the wooden coaster if Universal feels like splurging.
Universal Monsters-I want to see it here as much as you guys, but with the Mummy flopping and the Dark Universe going inactive (though Bride of Frankenstein is still in development and a small set was created that looked very close to the sets of the 30s) it may be dead. I could see them coming back as part of a retro land hopefully as a dark ride, with black and white visuals and a F0rbidden Journey level of polish, but those seem unrealistic.
Star Trek - I am tempted to put it under the unlikely or not happening, but unlike Warner Bros (Harry Potter doesn't count), Viacom and CBS are very willing to license their properties for rides and other things. The success of the next series will determine if it gets greenlighted, but I think it will be unlikely. A dark ride or a ride a la the Millennium Falcon ride will be the centerpiece, along with a lot of shops/restaurants, but nothing else will come.
Going to take a break on this as I have class. Will do the unlikely/not happening next.
