I guess my problem with this years arc is that we really know the Doctors not going to die at the end of the series. I'd just as soon get the damn thing over with and get on to more interesting stuff.
That's not the arc at all. The arc is about how the Doctor is going to get out of dying. We've already been given two clues as to how this might happen - one being the Gangers and the other being, of all things, Miracle Day.
You mean Torchwood's Miracle Day? No. That won't even be MENTIONED on Doctor Who. The "Blessing" won't come into play. At all.
For one thing, it would require other people to have watched Torchwood to get it--even the kiddies. And the BBC won't want kids watching it...
My bet is something Timey Wimey.
