Even if the Stormcloaks canonically win in Skyrim, they probably wouldn't show up as a joinable faction in the next game. We don't even know how many years will have passed between games (Oblivion occurs 200 years before Skyrim). The Stormcloaks could just be dissolved into just a general military force for a sovereign Skyrim.

The Fighter's Guild probably has presence in Hammerfell, and the Mage's Guild equivalent will probably be either the School of Julianos or possibly The Synod or the College of Whispers (likely not the Synod though).

And actually, I'd like to see Jyggalag come back in the next game. He needs more exploring. It would be interesting if it featured him as part of Sheogorath's quest. Perhaps you have to pick a side between them during a quest or something.

I would like to see the return of the Morag Tong. They were dissolved after the Red Mountain erruption, but made a pact to reunite and I'd like to see the effects of that in ES:VI. Possibly having some rivalry to the Dark Brotherhood faction again.

Finally, while I think the Dominion should definately have a presence in the game, the main antagonist would have to be something different. In each game, the main conflict revolved around something bigger than just a war between two races.
