I think were looking too much at the answer and not enough at the question. I don't think the reveal will be his name but basically just who is the Doctor at his core.
Wasn't it established in backstory for Seven at some point that the First Doctor had emerged from the Looms after The Other killed himself in rebellion against Rassilon? And that Susan was really The Other's granddaughter? If so, maybe he really is The Other. Perhaps that is the character John Hurt is going to play.
Part of me actually wonders, with its introduction in the Christmas special and the "The Bells of St. John," if the Doctor will somehow turn out to be The Great Intelligence.
I'm wondering whether, should the Doctor be established as The Other, Clara will turn out to be Omega and The Great Intelligence turn out to be Rassilon.
