^Yeah. Screamscape claimed at the end of last year that GoG would be a Vekoma Spinner. I think what has happened here is, after mccr put online pictures of the spinning prototype they have jumped on the rumour. But it still is that: just a rumour.
Sure until recently Disney fans were convinced that the F.L.Y. prototype was for GoG (even after Phantasialand announced it).
However though I think this has a chance of being true. Will be interesting to see it develop.
Do we know yet if the spinning on this is controlled (like Time Traveller) or free spinning (like Mauer spinners)?
