I think Tobi does it for his own fun. The park management were very impressed with his work, they thought it was great and invited him to the opening and made a big ideal out of him. In an interview the project manager spoke about how amazed he was with it and he followed the updates closely.
What makes Rookburgh different? Who knows. Maybe the park just really want to keep things secret, and release updates in their own way. It's odd. But sure we'll just have to see what happens.
Maybe they've promised him another invitation to be on the first train of F.L.Y. in return for not releasing his model.
(whilst stoping Looopings from going because they published a picture...).
Looopings are scum. The Daily Mail of theme park news sites. They have been on the war path for a while now with Phantasialand (the latest of many parks they have made enemies of). Among their lovely articles they have published illegally taken images, stolen images and write a load of rubbish about the park, including personal attacks on individuals who work for Phantasialand.
So they were not invited to the opening of Klugheim (and they didn't take it well) and I'm certain they won't be getting an invite to Rookburgh. I wouldn't pay attention to what they publish without fact checking it.
I mean Looopings is a site that thought Robb Alvey tweeting that he preferred Lost Gravity to Baron 1898 was newsworthy. And then got in trouble with him for using his pictures in their article without permission or crediting him...
And there was the time they bragged about how they pissed off Efteling by purchasing advertising space outside the park...
