I'm only speculating, but this could be the result of Vekoma's increasing their price tag for their thrill coasters, kinda like RMC after the success of their I Box track. Again, just speculating, but perhaps Vekoma had deliberately been selling their previous thrill concepts like Lech and Formula at an agressive price in an attempt to recapture this segment of the market (while still making profits from their family coaster sales). Now that many, many thrill coasters contracts have been signed - to the point the company could be saturated with demands from other customers - I presume Vekoma took the opportunity to raise prices, in line with their ambition to be a 'prenium' manufacturer so to speak.I still think the STC looks pretty decent for a family thrill cred, so I'm looking forward to it.
Bit confused how they're spending €14m on this though. I guess when you include groundwork and the non-coaster expansion they're doing with this project it makes more sense, but it's still a bit of a shock when you consider how cheap Junior Boomerangs are, and how cheap some of Vekoma's larger rides have been!
