I agree that I'd rather they didn't duplicate but I'm also not sure how many will have heard of a roller coaster in South Africa. I think if it was in the US then they would definitely avoid it.
You beat me to it, especially for SWO 2020 project, ABYSS, maybe inside and outside launch coaster hello Intamin.Would be a solid name for a coaster themed to the deepest depths of the ocean. That's a segment of SeaWorld's niche that is underserved in Orlando right now.
They've already announced that it will be called Mako. That's why there's only 4 options for roller coasters next year. There's MMXX, RMC Gwazi, Orlando's coaster and San Antonio's wooden coaster.SeaWorld San Diego is apparently getting a dive coaster next year. I think Abyss would fit that pretty well.
