Are the Stormcloaks or Imperial Legion the "Official" winners of the civil war?

I've finished the Stormcloaks and Imperial Legion, and both seem to have endings which could support an Elder Scrolls sequel in which a war occurs with the Thalmor.

I'm used to seeing Bethesda make games with choices that end up achieving the same thing, are inconsequential to a sequel, or are the "right" way to finish. I don't think the civil war's winner would be ignored in the inevitable "The Brief History of Skyrim" series or similar in-game books. It seems like a very important development.

Is there any additional dialogue or hints as to what side was intended to win the war that I might have missed? I've noticed in my current game that while the Stormcloaks have supposedly ousted the Legion from Skyrim, the Imperial Legion still appears to hold certain towns on their strategic maps.

Does that mean that while Tullius is dead, the Imperial Legion will just promote a new leader who will return to annex Skyrim?

Will the soldiers in the hidden wilderness camps continue to fight for the various garrisons around Skyrim?

If you intend to include dialogue or plot which could be considered a spoiler, please use the >! spoiler tag.

Solution 1:

I think it will turn out that both sides are the official "answer." Whatever side the Dragonborn sides with will turn out to be the right one. If the Dragonborn sides with the empire, s/he will eventually lead the empire back to health and defeat the Aldmeri Dominion as a great hero. If the Dragonborn sides with Skyrim, then s/he will eventually lead Skyrim into the collapsing sections of the empire and defeat the Aldmeri Dominion.

The Dragonborn has impressed gods and dealt with daedra. No matter who you side with as the Dragonborn, I don't think you're going to play second fiddle for long. Ulfric would soon be overshadowed by a Dragonborn who will come to lead Skyrim (if sided with Stormcloaks) and I think it is inevitable you lead the empire if you side with them (especially since

the Emperor is assassinated by the Dark Brotherhood no matter who wins).

As another poster mentioned, in the end it won't matter who 'won' this war. All the histories will record is the return and rise of The Dragonborn. After I beat the game (which I've done a few times now), I'm itching to go frag some Altmeri butt. Hopefully I won't have to wait until Elder Scrolls VI to do it!

Solution 2:

Bethesda has already written into the lore as it stands that other provinces have broken away from the Empire - Black Marsh and Elsweyr seceded after the Oblivion Crisis, Hammerfell refused to submit to the White Gold Concordat, etc. Future lore can sum up the Skyrim era with a simple "The Empire fragmented as provinces seceded or fell to infighting before finally being restored." So long as they don't list which provinces left the Empire, there's no need to specifically state how the Stormcloak Rebellion turned out.
