I would air on the side of caution and assume that they have made videos for each team so they can upload one right away when the announcement comes.
For what it's worth, Kevin O'Connor did retweet the video and HPBasketball replied to his post with "dm". Kevin has since removed the video. Don't know if that means anything or not, but HP may have said something in the dm about the clip.
Again, I assume that Yahoo made one for each possible outcome.
