I'm going to offer my two cents here for what it's worth and if we're being brutally honest, nothing has been as internationally defining or as iconic (thrill ride wise) as the Dreamworld Tower. Buzzsaw is certainly a local landmark through sheer presence alone, but it holds no weight against other great coasters of the world beyond being a one trick pony that's been repeated in several other parks around the world. In my eyes, it's essentially a modern Boomerang. It's not a bad ride by any stretch, it's a great bit of fun what with the whole "being upside down so high up with just a lap bar" element of things, but it's also no Superman Escape either. And therein lies where Dreamworld should move next. I don't need a magic ball to guess that Movie World will likely create something big in the next year or two and Dreamworld will need to really plug the coaster hole it has to be able to go up against Village as a whole. If I were Craig Davidson, i'd pick from two coaster types: 1) RMC Wooden Hybrid. Why? Nostalgia. Everyone's been on the Bush Beast at least once in their life. Adding a modern twist (inversions, steel track and even a launch) would not only peak local and interstate interest, but it'd put the whole park back on the world map as a place with an interesting, worthwhile coaster. Throw it in Blue Lagoon, and you've got amenities, facilities, and a stage for the ride to be built into ready to go. 2) Launched inverter coaster. Take your manufacturer's pick. Gerstlauer, Intamin or Mack. It just needs to look like Superman, talk like Superman, but pick up where Superman leaves off and roll a few inversions into the mix. It's a gimmicky tactic, but it's a marketable strategy where the general public can get behind it and go "Dreamworld's new one is like Movie World's one but it goes UPSIDE DOWN!" Think some kind of crazy Intamin Mega Lite, lap bars, the whole shebang. Ultimately they don't need another one trick pony, the park is full to the brim now of them. They need a Thunderbolt successor. Iconic, impressive, long and unlike Thunderbolt, actually enjoyable to re-ride.
