Tim, you are on something here!
Phantom Black R8 is in VIP salon at Audi Paris stand! My brother saw it in person, but no pics were possible! Well, he took few any way(mobile phone camera).
If you watch that AMS se video carefully you could see few interesting things on that R8:
-seats in very light grey(almost white), Audi Exclusive option
-Ceramics brakes

These options are not yet even on official German price list.
And there were a difference in brochure! Normal(smaller!) brochure for all visitors and thicker(with info about Exclusive options, Ceramic brakes etc.) one only in VIP salon. You could also touch and feel new lagguage set for R8(similar like F430 or Gallardo sets).
