Not sure if you can really compare this to Rip Ride Rockit; Falcon's Fury is delayed because it is first of its kind; Rip Ride Rockit was not delayed because it was a first of its kind revolution thing.
The delay is partly BGT's fault as well, they were too optimistic and announced an opening date even before any tests had been done.
In any case, I can't wait 'till it finally goes open and ride this thing
