The fact that we've yet to see any real images from James Cameron's Avatar is starting to feel less like a canny marketing trick than a deliberate attempt to annoy us. The movie comes out in six months! Throw us a bone here! And adding insult to injury, they're starting to do a little marketing not for the film, but for the video game, which is on display at the E3 convention in Los Angeles.

But on hand they've also got a model of the heavy loader from the film, which Collider's Frosty snapped some pictures of on the convention floor. He has no idea what it's for, and neither do we-- it's essentially what we saw in the concept art that MarketSaw posted last week. But take a look at what you see below, and head to Collider for even more images. Theories welcome.
