I was a fan of the Wheel of Time series back in my high school days, though I stopped reading after about book 8, in part because of my concern that Robert Jordan would die before completing the series and leave his readers stranded. Today I heard news of his untimely passing, just as he was working on the 12th book. Many of the books run 500+ pages, so what you basically have here is an immensely long fantasy epic, full of foreshadowing and stagesetting for a climactic final battle... and no ending. Yikes.
I don't even have an intuitive sense of what to say about truth and falsity about incomplete fictional works. Will Rand al'Thor die in the final battle? Before, we thought that question had a correct answer, though we didn't know for sure what it was. Were we right to think it did have a correct answer, or does Jordan's death make it the case that we were wrong? If it did have a correct answer, does it still?
