Gran Turismo for the PSP launches this Thursday, after years of waiting. Stephanie Toshimoto, over on the PlayStation.Blog, has posted the TV ad campaign for everyone to view (see below). The advert centers around the Corvette ZR1 vs. PSP racing against each other on Mazda Raceway Laguna Seca in Monterey, CA. And be sure to check out our newly re-designed Gran Turismo website that launched last week where you can find the latest news, trailers, and content.
