That is a shame, I really hope they include that in either a DLC or with the expansion. It would also be fun to attend the moot.
If the moot does happen, the only thing that would be different is that if you side with the Stormcloaks, Ulfric becomes High King. However, if you side with the Empire, then it is Elisif who is crowned High Queen.
Hehe that would be fun Nitron ^^
Don't forget that suddenly a dragonborn is running around Skyrim, whooping everyone's butt, and possibly the thane of every hold...not to mention the only person who's making Elisif's and Ulfric's continued existence a reality. I wouldn't be surprised if some citizens or a few jarls wanted you to be king or queen yourself. Or if you side with the Blades, I wouldn't be surprised if they helped you take it all by force (if you look at their dialogue, the one thing that seperates them from the Greybeards is that they believe power is a good thing).
