The Coaster Views has posted on Youtube a night vision video which reveal all about the new Harry Potter Escape from Gringotts ride... if you really want to know it, as it's difficult to find a video with more spoilers of the ride than this one.
That said, it's a particular interesting video as it shows decor elements along the ride that you can hardly see on the others videos as well as the track "drop" during the first scene.
You're warned, watch it at your own risk!
Edited 7 / 24: If you've not watched yet the video i'm sorry to say that it's too late as Universal has blocked it on youtube and it is no longer available. No big surprise as the video was showing so much of the ride that it was probably "too much" for Universal!
