Yeah, I was talking more about cars that are new to Forza 4. Since we know some of the cars in the Porsche Pack are new to the series, those are the ones I am most interested in.
I'm sure they'll sprinkle the new blood in at regular intervals. Then again the "new" Black Swan Racing GT3 was mostly a replica of the existing GT3-RSR.
So until they reveal a 928/918/981, I won't consider anything really that new.
