I'm going to hedge an early bet on an Intamin thirteen style ride with the piece of track that drops vertically. The only existing model is in the UK at Alton Towers, and the vertical track piece drop could easily be the largest in the world.
It fits all the info that's been given, and would be a sensible fit for the park since they've got several major thrill coasters already, and this would appeal to a slightly broader audience while strengthening that line up against the other parks in the region that are getting new coasters.
I'd be pleased with it, as it lends itself to extensive theming and an immersive environment.
