Just had a spin on the preview build of wipEout HD, thought I'd share the experience with you (without spoilers, of course).
First off, it's BLISS (but you knew that already).
Steering with the analog nub needed a bit getting used to (and after 3 hours I still didn't quite manage the hairpin at Chenghou), but it definitely works, and precise.
The pressure sensitive R2/L2 is great for sophisticated airbraking, however the double tap for sideshift is quite hard to pull off consistently.
Steering with the sixaxis works, technically, but is useless at high speeds (read: anything above flash), but sixaxis for pitch control is bliss.
Zone mode is pure eyecandy, although a bit too easy imo. Zen state is SWEET though.
Photo mode works perfectly, took 3 snapshots for you to ogle at.

That's it for now, will play some more tonight and answer whatever questions I can.
