Wired has a kickass gallery and explanation of Terminator 4 concept art for your viewing pleasure. Post apocalyptic earth looks something like what we’ve seen in the last few episodes of Battlestar Galactica, although I keep having flashbacks to Wall-E as well. And honestly for the first few I thought that I was seeing new Transformers art, as these kinds of overly complex metal robots tend to blend together after awhile. But come on, that scorpion tail thing? I’m pretty sure they used the exact same prop.
