Iron Man director Jon Favreau has confirmed that you'll see an official version of the footage that was shown at the San Diego Comic-Con online soon:
"I hear you all loud and clear. You want to see the footage that we brought to SDCC. Why not post it in HD instead of having everyone download a grainy bootleg? I agree. I am trying to get a version out to you ASAP. This is a big movie, however, and it takes time to get the proper approvals from all parties involved.
I am happy to report that both Marvel and Paramount have agreed to get a version of the footage out to you very soon. I will report the specifics when I get them. Thanks for your enthusiasm and patience."
This can not come fast enough.
