Press Conference Playback?

First I hope its ok with it being E3 to post this question in here but anyway is there anyway to watch the press conferences again? That might be an odd question but I actually wanna see sony's press conference tomorrow but will be at work. Is there any site gametrailers, g4, etc. that have playback for the conferences?

IGN typically does, but it takes them a little bit to get them up on their e3 site.
