I doubt it'll be removed. Like, really doubt.
It gets the same type of wear and tear as other coasters (hairlines in the track / hairlines on train weld joints / wheels / restraints / everything else) It doesn't make it any different to other coasters. It probably does cost more to maintain this type of ride, and more will go wrong with it, but it doesn't deem it unsafe for it to be removed. It'll just get sorted.
Did you know that the reason for one of Swarms train to remain out of action for a month was because of an unusual amount of hairline fractures? No, well you do now. What did Thorpe Park do? They sorted it.
Remember the restraint snap with Furius Baco? This happened on Stealth too, only it was out of operational hours. Its not an uncommon problem with this seat / restraint type.
So where the rumours have come from, I'd like to know because everything that is wrong with Furius Baco, are all common attributes to owning an overly-intense roller coaster.
