^^^ i think it won`t be a big flume like in tripsdrill! Just a short one with an elevator (and i hope a short darkride section in the castle before it
), then the big drop and then a short turn around back to station... maybe they add some nice theming elements during the ride. But what seems to make it necessary to change the theming is the height of the lift and the drop... Its much higher than their first plans, where the flume starts under the lifthill of the coaster. Now with a height of 25 meters is about 7 meter higher than the coaster with 17.5 meter. So i think they decided to take a castle to hide the high elevator and get a good adequate theming that fits to the park.
