My theory for their departure
the Angels are like the ones in blink, they take people and drop them off in different points in time. My guess is that the Angels grab Rory and Amy and deposit them in some time period. The doctor has no way of knowing where they have been taken to. It effectively writes the Ponds out of the series but leaves it possible for the Doctor to find them again for the 50th anniversary (should Karen Gillan and Arthur Darvill sign up for the special).
