I talked to the person who initially told me about the new coaster plans and it may truly be a "first of it's kind" B&M coaster coming in, and not just a wing coaster.
Some time ago they trademarked a "Surf Coaster" design (
B&M Trademarks New Coaster Type: "Surf Coaster"), and the new rumor is that it may be the new coaster coming to SeaWorld.
This would make a lot of sense with 2021 being so competitive for the Orlando market. While SeaWorld isn't in the same league and challenging Disney and Universal, they are focused on the annual pass/local market and need to do something big to keep them coming. With the Jurassic Coaster, Tron Coaster, and Guardians coaster all offering big new thrills, they feel they need to do something I'm sure. A first of it's kind coaster would certainly make a splash even in the big pond of Orlando.
Perhaps this is a variation on the Wing Coaster design and that caused the confusion?
