Ahhh you say that, but I decided to go on an internet hunt and found the Audi UK RS3 press release. Ok, not sure anything will jump out as anything we didn't already know, but still handy to know how a few things fit into the trim hierarchy and remember this press release is for UK Market, not just a german rehash.

Summary:
Four trim levels confirmed - RS 3, Carbon, Launch & Vorsprung
Speed limit - RS3 limited to 155mph (So I suppose Carbon also limited but with the option of 174mph if you have approx £1500 to burn)
Launch & Vorsprung limited to 174mph (well that's another approx £1500 on the price)
Optional - RS Dynamic pack will up that to 180mph.
Lights - Standard LED on RS3 trim
Matrix LED on Carbon, Launch & Vorsprung
Roof of Saloon in Carbon Edition trim will be brilliant black
Head up display available - doesn't say if this will be option or part of standard trim(s)
Seats - RS Seats with anthracite stitching as standard
Option Fine Nappa seats
RS3 & Carbon fitted with Flat bottomed steering wheel
Vorsprung gets round steering wheel
Obvioulsy RS Sports Exhaust and Adaptive dampers are on the option list as well but I was hoping (dreaming) that one of those might make it into standard spec.
So those snippets of trim info is my Day 3 update. (maybe I should have given you one bit a day to extend things, too late now)
