Sony Computer Entertainment (SCE) and Polyphony Digital have just released a demo for their upcoming Sony PlayStation 3 video game, Gran Turismo 5 Prologue. In Japan, that is. Since we're all still waiting for a release on our side of the world, let's check out two videos from Gran Turismo 5 Prologue's demo.

The first video showcases the Suzuka circuit and the Nissan GT-R Proto (mmm... shiny), while the second one is the replay video. The person behind the controller for this video seems very careful not to put scratches or dents on the car - it's technical driving at its finest.

Anyway, before we prattle on and on about the photorealism, the cars, the creases on the car's covering that you can see if you push pause just when the cars start, and the beautiful weather, we'll leave you to watch the videos. There hasn't been any announcement about when Gran Turismo 5 Prologue will be drafting to the shelves and the PlayStation Network (for North America), but we'll keep an eye out for it. In the meantime, enjoy.
