Actually, I take that back; I think I have an even better ending! You know how the Doctor always seems to have a knack for misjudging time? Well, wouldn't it be interesting if he said a temporary goodbye to the Ponds but arrived decades too late. That would leave us with three curious possibilities for their goodbye. 1: Amy is still alive, but Rory has passed due to old age. 2. Rory is still alive, but Amy has died of old age. 3. They're both dead and somebody close to them leads the Doctor to where they are buried.
My thinking here is that this would be tragic AND play on the Doctor's guilt. In a subtle way, this would also be him breaking his promise to Amy to keep her "still breathing" under his watch. So what do y'all think?
