Re: 5x09 Cold Blood (Grading/Discussion) SPOILERS!!!
Well at this point the set-up is such that it doesn't really matter either way - Amy won't remember if he isn't, and if he is, the death means even less. The outcome that I'd like to see now is that Amy's memory is restored, but Rory is not. Give his death some, albeit retrospective, meaning to his fiancÚ.
I don't think Rory's getting resurrected either, but I agree with you that the memory of him has to come back for the death not to be completely pointless.
I'm sure Moffatt is going to use Chekhov's engagement ring to achieve this.
