Excitement is in the air. I can smell it. It's disgusting, but at the same time strangely alluring. As if you didn't know, it's the finale of Doctor Who (6.40pm BBC One) tomorrow evening and it seems no one knows the fate of David Tennant's Doctor. There are tons of rumours suggesting this, that and the other (read a selection here), and I really haven't got a clue what's going to happen. So I'm throwing it out there and asking readers what they think is going to happen. Forget the rumours, forget the newspaper reports, forget everything... tell us what you think based on your gut feeling after you watched last week's episode. Tell us after the jump!
