on french forums, the debat about the trains being replaced is very alive.
Some says they have good sources saying the old ones would stay, having just the body remade to fit the new theme.
IMO, I found this affirmation to be odd. Ok, RnRc aged quite well for an 18 years old Vekoma (and running every day by the way !)... Maybe frome the mechanics point of view, the trains are in a rather good shape.
But, I can't help myself thinking it would make sense to have new ones. Of course, comfort is a main point. But comfort will always fit in the theme ! I mean, it's pretty obvious it will be themed after Iron Man, and therefore, Stark Industries. Stark Industries, in the Marvel Lore, is way ahead of its concurrent in technology. Wouldn't make sense to have a vehicule rough as f*** !
Then comes the money point. One one hand, it might be cheapier just to refurbish the olds Soundtrackets ... and god knows DLP loves the cheap solutions. But in the other hand, it would be a saving money thing to have the same spare pieces for both HyperSpace mountain and the Iron Man Coaster, whatever it will be called !
