I'm personally leaning more towards this being Revenge of the Bride: The Ride (Hey that rhymes!)
If they're going to do another indoor coaster, it should be what Gringott's should've been: An indoor coaster using the rotating cars but with practical effects and actually be a coaster. I'm hoping for Universal's take of Uncharted at Port Adventura or the upcoming Minecraft coaster in Chessington at England.
