In addition to what appears to be several never-before-seen locations, two of the most popular original tracks to the GT series which were absent from GT5 can be seen in apparently updated form: Seattle Circuit and Apricot Hill Raceway.
Before continuing, it is important to remember that just because these new tracks and locations have been shown does not imply or suggest they will be released as downloadable content in Gran Turismo 5. Curiously, the NSX video as posted on the official Gran Turismo YouTube channel makes no mention of GT5 in its title, unlike the Corvette Stingray clip posted just one day before.

Tokyo’s Ginza District
Shown during a collection of shots taken at Special Stage Route X, this tunnel appears to be some kind of spillway.
