What footage are we still missing?

Years ago I had a list of the footage we knew had been shot but had not been included in any of the EEs. Some of this PJ hinted might be released in some as yet unknown future edition. I seem to have lost my list and was hoping we could recompile it. So, what do you know or think you know exists?

From Wikipedia:

Dialogue from the Council of Elrond, such as Gandalf explaining how Sauron forged the One Ring.[10]
An attack by Moria Orcs on Lothlórien after the Fellowship leaves Moria. Jackson replaced this with a more suspenseful entrance for the Fellowship. Much of the lost footage can be seen as promotional material on the FotR theatrical DVD and tie-in books, documentary footage on the Extended Editions, and Trading Cards.
More Arwen footage, including a flashback scene of her first meeting with a beardless Aragorn (seen in the Two Towers teaser).
Faramir having a vision of Frodo becoming like Gollum.[13]
Famous footage of Arwen at Helm's Deep, cut by Jackson during a revision to the film's plot. Foreshadowing this sequence were scenes where Arwen and Elrond visit Galadriel at Lothlórien (seen in The Two Towers teaser trailer). The scene was edited down to a telepathic communication between Elrond and Galadriel.[13]
Théoden speaking to the troops in the armoury, prior to the Battle of Helm's Deep.
Éowyn defending the refugees in the Glittering Caves from Uruk-hai intruders.[21]
An unknown scene displayed in The Two Towers preview of Éomer lowering a spear while riding his horse.
A line of dialogue during the death of Saruman, in which he reveals that Wormtongue poisoned Théodred, giving further context as to why Wormtongue kills Saruman and Legolas in turn kills Wormtongue.[citation needed]
A conversation between Elrond and Arwen in a library in Rivendell, after Arwen decides to wait for Aragorn. Elrond leaves saying "I cannot protect you anymore." [22]
Aragorn having his armour fitted during the preparations for the Battle of the Black Gate. This was the final scene filmed during principal photography.[16]
Sauron fighting Aragorn at the Black Gate. A computer-generated Troll was placed over Sauron due to Jackson feeling the scene was inappropriate. Sauron is also seen in a beautiful form as Annatar, giver of gifts.[16]
Also at the Black Gate sequence, Pippin was seen in the trailer holding a wounded Merry, a scene which takes place after the Battle of the Pelennor Fields upon Pippin discovering Merry under the mûmak.
Further epilogue footage, including that of Legolas and Gimli, as well as Éowyn and Faramir's wedding and Aragorn's death and funeral.[23]


From me:

Sala Baker spoke once at DragonCon about a scene of Sauron melting gold over the fires of Mt Doom and letting it form around his finger as the One Ring.
An unknown dress exists for Arwen in much of the promo material: here
Arwen at Rivendell with Aragorn, seen by Frodo (this dress)
Arwen on the bridge at Rivendell -- Elrond: "I can no longer protect you."
Arwen hugging her father from her 'death bed'
There were rumors of Eowyn helping to deliver a baby in the Glittering Caves
Alternate lines for Merry & Pippin as Pippin leaves for Gondor
There is one image of Aragorn taking possession Saruman's palantir from Gandalf at Rohan
A line from the trailers: "Every path you have trod, through wilderness through war, has led you to this. Become who you were born to be." Not sure where it belongs.
