I think one (or more likely all three) of the Biturbos they're using will meet a sorry end. In both the '1 day to go' trailer and the 'Things to come this season' trailer which was shown during the episode, the blue Spyder can be seen being thrown into what looks like a lake. Disappointing really, but there we go.
As for the first episode...I won't spoil it for anyone that's not seen it, but I feel like they held back a little to accomplish a steady start which isn't necessarily a bad thing. Some parts were a bit strange though. The cinematography however was excellent as always!
