Nope. It was stored as h264 before they released webm (and then flash played it). When they released Webm, they started to convert all that stuff to VP8 (my guess is they should be through by now), so it's only VP8 now (via HTML5 or flash). End of story.
Adobe has not yet shipped a version of Flash which supports VP8, or WebM for that matter. They've remained silent on that matter since their initial announcement at Google IO last year.
