Here's the first trailer for James Cameron & Robert Rodriguez adaption from manga:

Sadly, it would be quite close to this year's "Ghost in the Shell" disappointment, and in a sort of way, similar in context story.

I'm not sold on the overall design, specially on animating actress' face to look like a real life anime. CGI looks good on some scenes and very animated in other ones. I hope it turns out a good movie, since I'd loke to see more (GOOD, and I do really stress this part) manga/anime adaptations.
