Funny thing is that I have no fear that the Audi R8 will dominate the above competition. From all the previews/unofficial lap times/etc. the audi R8(V8) surpassed what it was meant to do in the first place.
I can only imagine that If Audi can place a V10 in there, (that somehow weighs only a little more than the V8) and match that to a slick-shifting, reliable 6-speed manual............there will be no competition.
