The 3D nuts over at Market Saw have spent a lot of time chasing scoops about Avatar, James Cameron's upcoming sci-fi epic that, barely six months from release, remains a complete secret. And while Market Saw has come upon some bad leads in the past, today they've got a real one-- concept art from the film that will be included in the book The Art of Avatar: James Cameron's Epic Adventure.

The images not only give us a look at the Powersuit-- the machines that kinda resemble the big robot Sigourney Weaver steps into at the end of Aliens-- and a futuristic helicopter, but also contain glimpses of the faraway world this all takes place in. Head to Marketsaw for high-res versions of both images you see below. Since these images have been approved by Fox, you can be guaranteed that they're real, and also maybe count on seeing more where these came from.
