No.
(Seriously, we won't) It is something like a golden rule, the fate of all Player Characters is left to our imagination. Think, what if you had written an impressive and exhausting account of what happened to your Eternal Champion, or your Nerevarine, only to have a lter game directly contradict it. Even the usual bit of information we did get about the Nerevarine (the journey to Akavir) came in the form of a rumour. The thing to always remember with TES lore is that the most primal, and irrefutable lore is that which happens to you and in your imagination while playing an Elder Scrolls game. Beth are never going to do anything to limit that primacy, within good reason of course.
