i'v just finished the main questline for Skyrim and no i'm wondering, what happens next?

Do the blades regain full strength again and help kick the Thalmor out of Cyrodiil?
Do you become the next emperor?(since your dragon born and have to light the fires in the imperial city)
Does the dark brotherhood expand out of skyrim and become feared again?

What are your ideas for the next DLC for skyrim?
