I wouldn't even say the purple wedding would make a satisfying conclusion, Joffrey's death isn't even all that epic... It just, happens, a satisfying conclusion would either be dracarys, mother, or the small battle at castle black being won. Or the red wedding for the sheer number of deaths and the massive shock factor.
I never said that the PW should be the final scene, did I? I said it was a satisfying conclusion, because it is
. It concludes the stories of half the main cast, and kills off the most hated character in the show.
The best final scene would be the revival of Catelyn. Season one ended in fire, and season two ended in ice zombies; ending season three with the birth of UnCat would almost be like combining the two, as she is literally a fire zombie.
I have to say, I imagine most readers arguing for PW in season four would have been very disappointed if ASOS had stopped just before it took place, and we had to wait another year for it to occur...
And everyone else is an expert...say, what would they do in S4 if they have all "satisfying conclusions" in S3? Would that be "good television"?
Well without satisfying conclusions in season three, no one will tune in for season four.
Regardless, there is FAR more material in King's Landing AFTER the Purple Wedding than there is before -- Jaime's return, Oberyn's arrival, Joffrey's funeral, Tommen's coronation, Tommen and Magaery's wedding, Tyrion's trial, Oberyn vs the Mountain, Jaime scenes with Cersei, Tywin, Brienne and Loras, Tyrion's escape, the murder of Tywin.
Prior to the PW, this is what happens in KL -- Sansa meets the QoT, Sansa plots her escape with Dontos (who isn't returning for s3, so these scenes will be gone), Sansa is forced to marry Tyrion, blacklash to the RW, and some scenes building up to the PW.
