Looking at those pics, it is true that the track borders are a bit too vertical for my taste.
All wipeouts have had something in the 60º-70º range while the screenshots seem to be closer to 80º (data is subjective, your degrees may vary).
Exclusive preview content for WipeoutZone would kick ass. Not that I'm extremely confident of getting any. Game review sites and mags seem a bit tyrannic with development studios in this sense (exclusive content, being first to release some info and that kind of stuff).
