I agree about Sansa, but it wouldn't matter how much time they had: D&D absolutely lo-v-e Sansa, so she will get everything she wanted despite the sheer stupidity of her behavior on any number of occasions, and the fact that she betrayed a member of her family more than once, as well as all the wildlings who died because she wanted to be Queen of the May.
That's a big factor in my dissatisfaction with what I've read about the ending. D&D appear to have dumped the entire NK/WW story, all the prophecies, the whole history that went into the elements of that story (including Rhaegar's obsession with it)--and with it, marginalized Jon--to make the political squabbling over power the be all and end all of the show. Which is exactly the opposite of the point that Martin appears to be making: that the political intrigue is stupid and useless when an Apocalypse is brewing. It seems, tho, that D&D never liked the supernatural elements at all; only the intrigue appealed to them.
Based on the spoilers (and the eps to date this season), this was the wrong story for them to get involved in.
I wonder if Sansa will even care that her entire family will now scatter and leave her alone. I also wonder if anyone will consider her behavior treacherous and will avoid allying with her. If there were any justice, that would be the case.
