I would love to see the Bow of Shadow's, Dragonbone mail, daedric crescent blade, and the return of goldbrand and umbra.... what do you want to see?

This should probably be a poll. I'm voting for the spear of bitter mercy. You can add the words "of bitter mercy" to any item name and it's instantly awesome.

ALL OF THEM!
no.... more than that...

Dragonbone Cuirass and Goldbrand, because of the potential connectedness to the main quest. bliviongate:

Spear of bitter mercy, hircines ring, cuirass of saviours hide, volendrung, mace of molag bal, goldbrand, eltonbrand, bluebrand, trueflame, umbra, helm of oreyn bearclaw, bloodwyrm helm, sanguine rose, staff of worms, azuras star, spellbreaker, cowl of nocturnal, nerveshatter and the rings of namira and the khajiit

These are both excellent lists (for starters... :hubbahubba:)

I forgot daedric crescent, lords mail, dragonbone cuirass, bow of shadows, auriels bow, crosier of st. Llosia, cleaver of st,felms,, shoes of st.rilm, hair shirt of saint, and every other artifact I missed from daggerfall, morrowind and oblivion. I want my epic artifact collection like in morrowind

There aren't really any artifacts that I always seek after in every game... with the possible exception of Umbra, that is :3 As long as we see the majority of the existing legendary artifacts return, particularly a few that were in MW and missing in OB, I would be very happy. Spear of Bitter Mercy would definitely be a huge plus.

All I want are Umbra and Skull-Crusher. And I want Umbra to be a huge claymore again, not a stupid little longsword. I don't care if they give it Casts On Strike Soultrap again, I'll just mod it out if they do. Of course, it'll svck if they make it so weapons only have Casts On Strike again...

Eleidon's ward was awesome.

Azura's Star, definitely, especially if the magic recharging system follows the Oblivion style. I suspect that fire spells and weapons would be most useful in Skyrim, so Goldbrand would probably be very helpful (assuming they don't change the enchantment). It's hard to say right now, because the developers change the artifact enchantments around every game.

Hell yeah, this was my favorite shield in Morrowind.

Daedric Crescent, Saviour's Hide, Umbra (preferably with an owner that isn't a wuss and has a cool backstory), Goldbrand, Ebony Blade, Azura's Star, Daedric Face of God, Mentor's Ring, Chrysamere, Boots of Blinding Speed, and finally, The Fists of Randagulf (there's no reason they shouldn't be in Skyrim).

Chrysamere, fists of randagulf, boots of blinding speed, boots of the apostle, the 3 daedric faces,
