User blog comment:LoneGunMenWander/Should the Elder Scrolls Six protagonist still be the Last Dragonborn?/@comment-1600847-20160526165044

I highly doubt it will be. All 10 TES games have been in a new area, in a new year, with a new character, and a new plot.

The Dragonborn's story began and ended in Skyrim. At most, we'll get a book or a rumor explaining what happened to them.
