Below is a video from GTPlanet that was released on Christmas Day at the Asia Game Show 2009, which features a first look at two awesome new tracks, a plane and a helicopter in Gran Turismo 5 for PS3.
In one of the slides (below), Kazunori Yamauchi confirmed previous details adding that GT5 owners will indeed be able to record and upload their high-octane races straight to YouTube.
For those curious, the video game is slated for release next March in Japan, and Summer 2010 for North America and Europe.
To quote: "We first heard about the brand-new Madrid circuit back in April of 2008, and now we finally get to take a look at it.
We also get to see a new section of track from GT's infamous digital version of Rome.
There's new footage of NASCAR and WRC events, a helicopter, and what appears to be a Gulfstream Jet (?!!?!) on a runway with a Mazda 787B and Audi R10."
