Jet rescue hasn't been completely repainted, with new signage being installed for a new theme that was trademarked many months ago.
I think its clear to everyone what Dreamworld's plans are with the coaster, because between Parkz digging up trademarks, the obvious, ongoing work on site with workmen regularly seen, and progress obvious from the carpark, and sneaky signage and theming photos from guests in-park - we've got a fair idea on the end game.
Jet Rescue on the other hand has gone down for maintenance, repeatedly had its maintenance dates extended and eventually deleted entirely, photos of guests in park show what has to be fairly significant track\foundation work, and nobody from VRTP has said boo about the current situation.
It's hardly 'the same' situation. And like with many things - an open, simple explanation of the current situation from the park satisfies, and an obscure, silent park lets the rumor mill run rampant.
