I'm not sure if White-Gold Tower is going to be DLC. On the PC version of Skyrim if you turn no-clip on you can fly around and Morrowind, Vvardenfell, Red Mountain, Cyrodiil, the White-Gold Tower, High Rock, Hammerfell, and possibly Black Marsh and/or Elseweyr have been fully rendered.
But those could be simply for scale, and the presence of the White-Gold Tower might have been simply so that you could see it from certain distances at certain points of Skyrim.
I think it would be cool to visit Cyrodiil again and see how it is in the aftermath of the Great War. I really want to see Akavir or have the game deal with the Akavir.
Having further read his post, I think it's worth noting that the dragon that the elves refer to is Akatosh and not the dragons of Skyrim. The prophecy is really contingent upon understanding the origin myths of the cultures in Tamriel.
The understanding that my friend and I have come to is that through the usage of the Numidium, which according to the Arcturian Heresy (and thus of dubious veracity), Tiber Septim aka Talos aka Stormcrown aka Hjalti Early-Beard powered the Numidium with the Mantella in lieu of Lorkhan's heart (which the Tribunal had), which is a massive soul gem. In order to power it, Talos and his Imperial Battle Mage Zurin Arctus betrayed Talos' ally Ysmir -- said to be a Shezzarine or avatar of Shezzar aka Shor aka Lorkhan.
Somehow Zurin Arctus died in all this -- according to other accounts Talos betrayed him and used his soul instead of Ysmir's.
My friend and I decided that there was some weird stuff going on here and that somehow their three souls conflated, and the divinity inherent in whomever was the Shezzarine is what resulted on Talos achieving divinity. The Arcturian Heresy doesn't really make sense but it's the only version of the story that really explains how Talos achieved apotheosis, or at least provides an avenue for it.
Anyway, according to the origin myth, the distinction between the daedra and the aedra are that the elves consider the latter to be ancestors and the former are not. The aedra are technically weaker than daedra because they relinquished some of their being in order to create Nirn per the design of Lorkhan. Apparently Lorkhan is the trickster god because the other divinities didn't realize that they would be doing this, and that some of them, like Magnus, realized it and fled. The sun is the hole torn by Magnus in his retreat back to Aetherius so he wouldn't be tied to Nirn, and the stars are caused by lesser divinities.
The lesser divinities trapped on Mundus had apparently become mortal and began reproducing, with each generation of weaker ability until their divinity had become diluted enough that they were the Mer, or elves.
Which I suppose is why the elves hate Lorkhan, because I guess they think they would be gods without his fooling of the divinities into creating Nirn.
Also for the first technical (Dawn) era of Tamriel there was no concept of linear time until Akatosh, the god of time, established it with the Merethic era, which is when the stuff with Alduin went down. I guess the elves want to restore that.

My friend thinks it's notable that when you visit Shor's Hall in Sovngarde at the end of the main questline that he says the people there act as though Shor is still around.
I still haven't read the "mind-blowing" thread the guy links to, I guess I need to do that.
