Ron,
I belive you. My brother(he is in Paris) told me over the phone that R8 is the main star. Even guys from Porsche came to see R8 and they were pretty interested in it!
BTW, there are NO any news from Porsche regarding PDK or so. 997 GT3RS and Targa versions is strange orange(bronze?) metallic and this is it! Most of the people said there that 997 GT3RS is nice in Orange... But, no big buzz or interest on Porsche stand in Paris.
