Since there's just so much crazy speculation, i'll clarify: Dreamworld's CEO has gone on record to say that "areas" will be refreshed and repurposed. Adding to that, the Mine Ride, Log Ride & Vintage Cars will re-open by December this year. So here's some logic: if you wanted to be smart with your capex (and the major reason for the Mine Ride's closure was due to changing safety standards (mainly the envelope of the ride's tunnels) then if you've got a team of folks who are removing the Rapids Ride, it'd then be cost effective then to get them to work on the removal of the Rapids Ride, removal of whatever you need removed from the Mine Ride and have the Rapids Ride landscaped appropriately & ready for whatever you plan to put in there next in one hit.
From there, you, as an enthusiast can ask logical questions that flow on from that. If there's no Rapids reservoir, do you need any of the bridges or elevated pathways anymore? And if not, is that why there's a path being poured down the bottom of the Giant Drop as we speak? Is that why they've waited so long to install the electronic boom-gates for the train at Main Station? Maybe they were waiting to do two or three sets all in one hit? And from there, if i'm being conscious about capex, what do I, as a CEO, fill that land with? If I was Craig, i'd maybe move the Model T Ford Cars there. It's inoffensive, it's nostalgic, it's a great family ride and it would be dirt cheap to fill a large space with, especially with something that families love. It fits the old timey theme, and would help bridge the area well.
There you go. There's some serious thinking there that's based logic and facts that I would love to see on Parkz more instead of constant back and fourth over nothing that happens constantly.
As a side-note, Wipeout is being worked on as we speak. A lot of the areas where there was visible NDT have now been painted over with a primer.
