Drift God brings up a valid point. This could just be one of the several dozen demos that PD have made for car manufactures. But, it doesn't mean we'll get the car in GT4. But, then again, if it's a new car for the NA market, then why wouldn't they add it to the NA version of GT4, especially after going through the trouble of making the car for the demo?
This could be more proof to the rumor that the car list for the NA GT4 will be very different than the Asian version. This is very exciting news. I can't say I was completely happy with the Asian car list. So, this gives me more hope of seeing a better car list for GT4.
