BGT is due a new ride, 2019 might be the year.
SeaWorld have submitted trade mark applications for the names:
-Twisted Tiger
-Uproar
-Tigris
Rumours are circulating about what these names could mean, but most enthusiasts were pretty excited when seeing the first one. It kinda rings a bell, Twisted Colossus, Twisted Cyclone, Twisted Timbers...Twisted Tiger!?
However, the park have repeatedly said that Gwazi was due to be torn down, whether or not this includes the possibility of an RMC is unclear. Gwazi has been standing there for a good 3 years now, so to keep the structure I would imagine that you would need significant structural work, which I'm not sure SeaWorld are in a position to finance.
The other possibility is the Tidal Wave site, which is actually located fairly close to the park's Tiger habitats. A Premier Rides Sky Rocket II would fit well here, and whilst itwould be a clone, it would provide a cheapway to install another thrilling coaster at BGT to add to their already great coaster selection.
The speculation continues, something is definitely happening though......
