In all my playing of Oblivion and Morrowind I probably found 2, maybe 3 pieces of Daedric armor and I never wore any of it. Let's just say I'd be a little disappointed but it wouldn't be missed.
You never met a marauder in Oblivion after level 20, or went on the ultimate search in Morrowind to find all available pieces?
Then you'd better start playing again until TES V comes out!
Personally I was more for Medium Armor in Morrowind, so although I collected anything Daedric I only stored them for my "museum".
In OB, I had one char that wore full Daedric, but only because there was no better armour. If there will be a good alternative for Daedric, I wouldn't miss it.
But I doubt that it will not be in TES V. It's probably one of the first things the Devs were developing once they started on the game...
