Moffat has officially said Season 7 will be the last for Amy and Rory, "The final days of the Ponds are coming. I'm not telling you when or how, but that story is going to come to a heartbreaking end."
As we know, and were always expecting, it always comes to an end for the Doctors companions. But for many of us it will truly be a sad day when Amy and Rory finish their travels.
In an ideal world the two would get their own show Scooby style but that's probably only wishful thinking.
