No updates on that were given, but Walibi also never officially announced that layout either. So officially we do not know the layout yetDo we know if the layout's stayed the same since its IAAPA reveal? Parc Asterix's launcher has already changed layout multiple times if I'm not mistaken.
That was my initial thought too, given the amount of issues they've had with locals and building new rides. The site has a lot of trees and next to it, so it would make sense.Maybe dark green is a way of making the ride "blend" (if you can blend a 200 foot megacoaster) with the ride surroundings to avoid complaints? I don't know, it's just wild guessing since I have not been to the park.
