Heard a really interesting rumor today that yet another coaster is on tap for SeaWorld Orlando. Apparently the plan is a new B&M Wing coaster right at the front of the park as part of an overall revamp of the front gate area (much needed). The rumor is the entire entry experience would be reconfigured using part of the seldom used Bayside Pathway area and the new Wing coaster would soar over the revamped entry way (much like Gatekeeper at Cedar Point).
It seems like many parks are revamping their entrance areas (CP, Carrowinds, Hershey, SeaWorld San Diego) as the infrastructure has become dated and impractical for today's needs (increased security measures), and it would make a lot of sense for SeaWorld to do the same.
I'm not sure on a timeline for this, but I would think 2023 would make a lot of sense with the park's 50th and increased competition to make a real statement with a new entry and a new signature coaster.
