GRRM's interview
Just saw GRRM's interview where he reveals he had planned a more tragic end for Tyrion (ouch) and that he planned to kill Sansa but because she was "appealing" in the show he "might let her live".
I don't think that confirms anything either way on Sansa's survival, but if we consider the timelines of the book and the series, that does mean that everything GRRM wrote in the books was with the intent of her dying. Which confirms all that "foreshadowing" Jonsas/Sansa stans saw for QITN Sansa and Jon and Sansa marrying was all in their head (which we already knew tbf)
