(Spoilers Extended) My predictions for winds of winter and dreams of spring
(not in any particular order)
in the north:
Jon snow gets revived.
Sansa will be discovered as Sansa and the vale will go to war to put her in charge of the north (littlefingers survival is honestly irrelevant).
the bolton‘s are defeated because everyone hates them.
a stark civil war might happen between those who want Sansa to rule and those that don’t because woman/too andel/puppet of the vale/puppet of littlefinger if he is still alive.
if a stark civil war happens the free folk might try to capitalize on the norths weakness to not have to abandon their ways which Stannis won’t agree to if a stark civil war doesn’t happen the free folk will probably still go to war with the north do to miscommunication.
the free folk will lose leading to them using the horn of winter to bring down the wall.
the others just walk over the exhausted north and the defeated free folk Like weeds.
jon arya and bran flee/go south
in the south:
daenerys returns and under the advice of Tyrion uses harsher measures which work.
euron Wins the kingsmoot and attacks Oldtown but is repelled by aegon.
the sand snakes kill tommen allowing margaery to marry aegon expecting dorne to support anyways because he is the son of Elia (Which they might do.
aegon defeat the Lannisters at which the Dornish go home.
walder frey has died at somepoint causing the Frey civil war weakening the riverlands and allowing the others to once again walk over their enemies like weeds.
daenerys refuses to marry aegon and acknowledge him as king because she has dragons and he doesnt.
regardless of who wins and how the dragons inflict massive casualties Allowing the others walk over them like weeds just as they did the north and the riverlands.
the Tyrells are remembered as backstabbing opportunists who only ever sided with the losing side of every war they ever fought.
dorne is the last kingdom to fall and if they didn’t join aegon or want home immediately after they killed the Lannisters they put up a good enough fight with gorrila warfare to give Jon ,bran and maybe arya enough time to pull of critical assassinations that cause the others to fall apar and probably retreat.
more realistically due to the millions of zombies they have at this point and the magics the likes of which Westeros hasn’t seen In millennia the others go undefeated and conquer the world.
