Bit of a mouthful, although stranger names have been chosen in the past!
Just a couple of thoughts,
Could this be Abyss? I'm not convinced, personally I would associate Abyss with the deepest & darkest depths of the ocean rather than the Arctic. A lot of people seem to think Abyss will be for San Antonio, we will see. I do hope we see some decent theming on this ride though, you would think they would need to do quite a bit of theme work to make the arctic setting seem reasonable.
Also, with Shamu Stadium set to undergo a major overhaul for 2020 as well, we could potentially see an arctic style makeover to the stadium to create a more consistent area made up of this coaster, Shamu & Wild Arctic.
