After reading more, it seems BP has had video from the spill all the time (well for a while). From the original article I linked. Now this calls into question, how close are these subs? Anyway, it would seem to be more accurate info than what the surface guys have.
They actually just released some video, here. Maybe they are getting this from remotes operated from the sub?
I really hope you are right. Should be interesting to see what the experts make of a video announced on Twitter.
