I think everyones being abit harsh here!
To me the speed looks fine. I bet the view at the top of the tower is great and with such shallow banking I wouldn't expect anything faster! It's a great little moment before that big drop (which looks like it'll have good air) AND a frickin' launch. The rest of the layout looks like it has good pops of air and I think the inversion is taken at good speed.
It's no Intimidator 305, but I never thought it would be! Also you have to realise rides feel alot faster when you're actually on them, and this may even look slow due to how draw out the lower parts are, but flying along the ground with the wind in your face, I don't know, I'm just shocked at the negativity this ride is creating.
Meh, I know I'd enjoy it anyway, but then again, I enjoyed Thirteen.
Also, preview renderings of rides have ALWAYS made the rides look fast. They're full of fast editing and interesting angles, added sound effects and motion blur. Take a look at say... Intimidator (Carowinds) video, then watch a video of it's first test run! I thought people would've learnt by now to take them with a small pinch of salt.
