Here are the rumours I have been hearing
IOA - I heard a good rumour that for IOA's next big Coaster, it will be a B&M Vertical Drop Coaster, It will most likely fit between JPRA and DD somewhere as IOA own all this land for future devolpment, It would also be the perfect ride for IOA because its heavily technologily advanced which is what IOA want all their rides to be
I too have heard the rumours of the Jeep Ride, this would also go near JPRA to fit in with the jurassic park theme.
BGT - There is still strong rumours BGT will get a Hyper and will come in 2002 fitting in with the 3 year rule. I have been hearing the rumour for over 2 years now, so Its bound to happen, Look for an Apollo's Chariot style layout. Another reason why it will happen is because I heard they were gonna see how popular Apollo did at BGW for 1 year and then consider one for BGT. As for the location, It will most likely go behind The Pyhthon.
Although Florida does need a Hyper, I also heard BGT may get a B&M Vertical Drop Coaster, when Gwazi was announced, BGT done a survey asking people what people wanted to see after Gwazi was built, the winner was a B&M Vertical Drop Coaster, I am still guessing they will get the hyper in 2002 though, but who is to say this wont happen for their next big coaster in 2005;)
