Since this is just speculation from some website, I will try to back it up from a more reputable source (me!

)
Porsche sent out 'feelers' to all of its dealer body/customer base in the US. They sent out mailers to all previous GT/GT2/ and multi-Porsche owners to feel out interest in this car. I assume that is where the article is basing its information from- these "feeler" surveys that went out last month.
*fingers crossed*
I want to drive one! And if they make it.. *grin* I will!
