Anything is possible. Before Magnum was ever conceived by designers, just think about how many people might have thought of a giant coaster. Others would have laughed in their face making fun of them. It did happen. Just as Millennium Force stormed through and broke the 300 foot mark. I can almost certainly promise you something bigger will show up. I never doubt anything. Ideas pop up everywhere, just be on the lookout for the first of its generation. I am very adament about the arrival of newer designs.
I heard port aventura in spain was going to get a coaster. They've been known to make really good rides. Has anyone heard anything like this. Maybe they will be making a giga. Oh and by the way what comes after giga?
