Here is a new info, just ten minutes old info from my Audi friend.

Official R8 press presentation is in Las Vegas, Nevada, USA on Januar 17th 2007! Audi already sended 25(only!!) R8s to Nevada. There will be Audi race instructors as well as driving on the Las Vegas Race Track. Members from car press from all over the world will attend this presentation.

...and now special info... In February 2007 at the same location there will be dealers/distributors R8 intro that will include costumers with orders!!!
So, if you are interested to try R8 at least TWO months before Showroom intros call your dealers on 02nd January....

Very nice info indeed!
