Updated: The Making of Street Fighter IV from Comic Con

This presentation was lead by Yoshinoro Ono, SF4's producer and it has some good information in it.
Here's some of the juicer bits along with a video that Rez2cool posted on YouTube of the Q & A session and the Chun Li anime sequence that starts at about 2:49.
• Seth Killian said that the winner of the poll for the new character most people would like to see was Cammy, and that this choice will be taken back to Japan and discussed with the Street Fighter IV development team. It's a reasonable assumption that Cammy will be in SF4 in some fashion after this announcement and her being featured in the new anime video.
• He mentions that they're hard at work on the home port, given that arcades are a dying breed in the U.S.
• Further announcements on what Capcom has planned for the anime sequences we've been seeing will have to wait a bit longer. i.e. they have bigger plans than they've currently revealed.
