I JUST DON'T KNOW
Rickon without a doubt! Bran will technically be alive in the same way Bloodraven is but he's not leaving where he is. I don't know about Arya and Sansa. They're both involved in some really heavy trout. Sansa's wolf is dead so I will take it as symbolism!
Bran and Rickon are gonna snuff it. The rest will pick up scars (be they physical and/or emotional) but will be around for series six.
Jon Snow and Arya, not sure about the others. Although if all the things said about wolves and winter are any indication, the Starks may be the only ones to survive winter.
I think Sansa will never be a Stark again, tbh. Something is going to happen so that she can never reveal her true identity and will live distantly from the North. I think that's the symbolism of Lady getting the sword early on. I've thought similar things about Arya, that she will never venture to the North again, since Nymeria was chased away buuuut after the whole "Starks are wargs" thing I am having second thoughts. Too much Tully in Sansa and Robb, maybe! Not Wargy enough.
Signature by rubah. I think.
i think the sisters are gonna live.
everything is wrapped in gray
i'm focusing on your image
can you hear me in the void?
Jon, Arya, and Bran.
...
I want Sansa to live.
I also want to see Rickon make a reappearance some time and stab up some guys or something.
I'm with foa on Sansa. I do not think Arya will make it purely because we expect her to; I think she'll meet an untimely end. It's too much for GRRM to give his characters a satisfying end, though he does seem to have a place in his heart for Arya.
I think Rickon is out of the picture, mostly. Jon is gonna make it, Arya will die, Bran will stay where he is and Sansa will be a disassociated Stark.
Jon Snow. Possibly Sansa.
I think Arya will die.
