Id say pretty soon here. FL announcement was around Aug 15, 2014, and they said 1 or 2 weeks before that, that there would be a big announcement. GG shut down on about Sept 11, 2015. So, the longer we wait, the smaller the ride will be, if we get anything next year, and the less likely that we will get anything...But we could also start seeing construction starting for something really HUGE soon, that would open 2 years from now.
I think i saw the old Train robbery stage being torn down near about July 2012 ish...
