If the YouTube video isn't taken down
I could be wrong with what I'm about to say, and I realize that it could seem to be only about a day and a half since the video was reported, BUT even given that time frame, to me it seems like the fact that the video is still up could be a good sign that it could remain so. And the reason I say that is because in the past WB has acted swiftly if not instantaneously to have their stuff taken down from YouTube and other places. Presumably you know who received the report of its upload in a timely fashion in whatever manner it was delivered (e-mail, phone call, whatever), so chances are if you know who would have reported it to WB, they would have contacted YouTube by now and the upload would be no more (I've know of instances where their stuff has been removed in less than 12 hours of being uploaded) - but it's still there. And along with all the questions already surrounding the origin of the video, that fact begs several more questions...
But I suppose we will see...
