You can actually tell a lot by those blue prints. There are banked airtime hills. That video that was posted is actually pretty spot on. If you look closely at the leaked blue prints you can see lines where the supports are so you can tell where there is height. The turn around starts low to the ground and rises quickly.
The helix also appears to be pretty high in the air based on the length of the suppprts that are visible
Also, look closely at the track. You can see lines on the sides and so where there is banking you can tell. The second hill is banked to the left. I actually traced over the track in photoshop, not just as one solid line like other people had, but zoomed in and traced all three lines of the track so you could see banking. I also highlighted the supports in red so you could tell where there is height but when I posted on here it was removed because it was a traced copy of the leaked blue prints. I would be happy to PM to anyone interested though.
If this is real it will be short but pretty intense. That video someone posted on YouTube looks to be spot on
