Man, I’m looking at an overhead shot of the park right now, and it appears like they have no room left to expand in the park. All of the expansion plots have been taken over by Antarctica, Mako, Sesame Street, and Infinity Falls.
Although, they could always use some of the parking lot near Sesame Street, or the backstage area near the entrance. But there’s no room for a coaster unless you do that, especially not for one that goes over the water. So Wave Breaker is not happening.
