I am not. EA owns the exclusive license to Porsche. They sell a sub license to MSFT for Forza, read rumblings on the web they will not to Sony for GT5 because they see GT5 as a competitor (I know odd).
(wonders if Peter Moore ex 360 honcho but now head of EA Sports has anything to with that)
So they have RUF which are modified Porsche, like Callaway is to Corvettes and Saleen is to Mustang.
