For the Dark Brotherhood it's possible that the next game is so far ahead that they died out regardless of what you decided to do

The Civil War probbably won't matter either, and as stated previously both sides will be weakened

Lastly, for Dawnguard that dosn't seem like it evn needs to be mentioned at all. You join Dawnguard then you killed some vampires, get some Troll mercs and a magic warhammer. You join the vampires than you got a castle, can summon Gargoyles and got some jewelery.

Or Bethesda could simply just decide to ignore all that and leave us wondering what happend. Would that piss people off? Yeah but it's easier for them and they know people will still buy the game.
