So as it is kinda confirmed that something big is coming within the next 2 years (won't rule a 2018 opening out as 2017 could be mostly construction, so it's still a big investment that year) the question now is, what is coming?
For location I'm guessing the land between to the Mountain Rafting, Wüstenflitzer and the old log flume.
Why?
The couple of old flat rides that were there have been removed and the Lego store has, as far as I know, been moved to the entrance of the park. At least it isn't on the park map anymore...
And what is going there?
I'm guessing some kind of water ride (Intamin AquaTrax FTW!).
No srsly, The log flume they have rn isn't themed, pretty old and generally unexiting, especially compared to its competitors at EP and Phantasialand.
BTW, If it's a water ride I can see them removing the old log flume entirely for additional space!
So and now we get to the probably pretty unrealistic dream I'm having since some time now for this park.
A launched B&M flying coaster over the lake!
Well you're allowed to have dreams... :/
