Ok, so this is according to the Sun, so all might not be true, but there are a few un-answered questions, because, as said, rory is not seen in any of these scenes, and it is after the big 'cliffhanger' at the end of series 6, as Moffat said that it will be:
"an enormous, game-changing cliffhanger for the Doctor, Amy, andRory. It will change everything for them. You will see the Doctors life change forever, you will gasp in astonishment at the true nature of his relationship with Amy, and you will cry out in horror as Rory Williams stumbles to the brink of a tragic mistake..."
if rory has stumbled into a tragic mistake then maybe it is him that made the TARDIS explode, and the mistake could be that he ends up dying for real? Because if you think about it, he is dead really.
and amy's relationship with the doctor?
maybe she could be her daughter or something?
I don't know, there's too many maybe's...
