You're really starting to shit me. You make a lot of broad reaching statements, but you never provide any support for them. A lot of them could be true, but without citation or support, it could very well just be your own assumptions, which you present as fact.
The Maurer Rides website still lists Skyloops \ Skywheels (XT450, XT150) on their website under 'specials'. The same section lists:
Drives
Inclined / Vertical / Up-side-down Lift and LSM Launch
Vehicles
2- / 4- / 6-seater as well as coupled single vehicles and trains
Restraints
T-Bar, Lap-Bar (X-Seat I), Overhead-Bar (X-Seat II), Flexible Bar (Belt)
So I'm calling bullshit...
(Interesting side note - has anyone discussed SPIKE yet? )
As for your suggestion that Dreamworld are going to have an issue getting manufacturer cooperation - just because a manufacturer doesn't sell the product anymore, doesn't mean they don't continue to provide support to their customers... and to suggest that is just stupid... how likely do you think another park would be to buy a Maurer product if they knew that as soon as the company decided to stop making that model, they'd be on their own?
