I think there's been a few rumours circulating that silkstone & co have something to do with refurbing it.
Sounds like complete utter bogus to me, but then again this is Thorpe Park we're talking about... 👀
In all seriousness though, Thorpe did reveal in the Passholder group that they had been intentionally messing about with everybody by changing the imagery and toggling it on/off on the app, but they also (probably a freudian slip if anything) said "So, c’mon what are everyone's predictions for our spooky dark ride?! 🤔" so pretty much all but explicitly confirm that something is happening to it.
