I'm not sure if anyone else saw this trailer or not, but I was watching basketball this weekend, and I saw it. During the trailer for Grindhouse, there is a female merc who has a detachable gun for a leg. That is so awesome! It immediately made me think of Shadowrun. That 10 seconds of video alone has made me want to slam down the cash to see this flick. Quentin Tarantino and Robert Rodriguez rock.
Here's the only still image of it I could find, but just watch the trailer. The capture can't do it justice.
