Rose in The Waters Of Mars?

I have been hearing about the rumour that Rose has been spotted in The recent Waters Of Mars trailer but until now i haven't seen any images of the still. I watched the video and could see the woman but not for long enough to see if it looks like Rose. But now, thanks tohttp://lifetheuniverseandcombom.blogspot.com/, this image is from his site but it is from the trailer.

So what do you think. You can definatley see that it is a blonde woman holding what looks like a baby. Also she looks as if she is looking into a webcam or some sort of camera. Could this be Rose? But how can she be what would seem to be sending this message to another universe. Is she warning the doctor about the masters return? Who is the baby. We know that Rose now has a baby brother called Tony in 'Pete's World' but is this him or is this Rose's child with the metacrisis doctor?

What do you think? Rose? Tony? And how will this fit into the story of The Waters Of Mars?

See Ya,
