The two guys pictured below weer spotted doing leg and truck-powered laps of Bathurst's Mount Panorama, where they've taken photos of one of Australia's most recognised race tracks. That's not all, because audio from intrepid's souls phone camera definitely points toward the raceway being featured in the next instalment of the Gran Turismo series.

The clip is below, and you can hear the guys talking about it, with a subtitled version available, too. There's also a thread on the GTPlanet forums, where people are convinced that one of the Polyphony Digital guys says "GT6". Of course, this isn't 100-percent irrefutable evidence, but it does have more credit than just a shot of two guys posing for a photo.

Unless this is a DLC pack for Gran Turismo 5, that is. The other question is, if this is for GT6, would it arrive on the PS3 or the PS4? Polyphony Digital do take their time releasing games, so I would be willing to put some money on this game hitting the PlayStation 4.
