Found this on another site, The 4D could go to Thorpe Park maybe?
2011 - Roller Coaster - Rumor - (5/2/10) I’ve heard an interesting rumor claiming that the rumored prototype B&M coaster going to Gardaland may end up being even more of a “test track” than I had thought. The location of the park itself has come into play since it is only about a 4.5 hour drive from B&M’s headquarters Monthey, Switzerland. This close distance will allow for B&M to come onsite often as they work on this new concept, which may be done in two phases.
The first version of the new ride concept is still said to be somewhat like an S&S 4th Dimension coaster, but without the spinning seats, so I’m guessing it may end up being more similar to Intamin’s WingWalker design that so far has only been built once at PortAventura as Furius Baco. In B&M’s case, I’ve heard that they may very well want to produce their own version of the 4D concept, complete with spinning seats, but wanted to build a non-spinning prototype version of the train first. The goal here is to not only perfect a new train/track pairing design, but to also gather all the practical G-force and Accelerometer data from this new train deisgn before trying to implement any kind of crazy spinning seats.
So what is Gardaland getting out of this special arrangement? Not only do they get to have B&M’s first new prototype coaster design and all the eyeballs around the world that will follow it’s development, but I’ve heard that the park will be getting this ride for a cost not too much more than the cost of materials and labor. Of course this last part is only a rumor, and nothing anyone would ever likely verify as these kinds of deals are very secretive.
