Found this forum a few days ago and just read the whole thread... A bit of my speculating about some of that theories had to come, nen? XD
Sweet Cersei the Bitch - I must admit I really enjoyed her POV, as relating events in King's Landing. I don't feel any sympathy towards her, but I can't hate her either. She's, well... not nice. A bad girl. Apart from that evil business (looking at Qyburn's doing), she isn't a good queen - and I don't mean by it her decisions only. Not being exactly stupid, she would make a unexceptional Lady, but she fails to see herself objectively, or at least partly objectively. Not everyone in the game of thrones is a genius, the first step seems to be understanding one's own weaknesses. How on earth Cersei was supposed to win, while she considered herself the most intelligent of them all, never having doubts longer than for a while? Besides she is too emotional, as said in someone's - Jaime's? - POV. She loved Jaime, despised (or even hated) Robert, but having her brother's child and not Roberts wasn't a wise move. Let's consider it: even if noone had ever discovered the truth, it would have been pointless to have pureblooded Lannisters - always named Baratheons... Who would know after twin's death? Perhaps Joff or his sibling might have been told, so as to ensure Lannisters/Baratheons will never forget. But the very moment someone had told it aloud, even after few generations, anyone powerful enough would get the perfect reason to destroy the royal family as bastards having no right to the crown. If it's never discovered, it does no good to House Lannister. And risk turned out to be serious... For Lannisters, including Cersei, for Baratheons, generally speaking: for everyone interested, it would have been better if Cersei had been careful not to give birth to some bastards instead of avoiding having children that was needed. While her decision is reasonable as loving woman's, it is unreasonable as queen's. Same goes for her feeling like horse - she screams something about being treated as a body, to produce children. That's not nice, but she can't change the people of Seven Kingdom's views in instant - wise woman could use it. Not being treated as an equal to men by her father makes her think herself better than she is in fact, so she underestimates half the people she deals with. And even if she made a good queen, there would be still Daenerys.
Arya - my favourite one from AGoT, though later I grew to like most of POVs. I don't believe she'll become a faceless woman - she is too much of a Stark for that. Even when she really tried to be Cat, she chose name that resembled the one of her mother's (she did something similar earlier, at Harrenhal?, telling Lord can't-recall-his-name-right-now that her name is Nymeria, but she's called Nan), and called the ship her "father" sailed on Nymeria as well. And she continued to have wolf dreams. She threw away her things, but hid the Needle, planning to get it back one day. IIRC, there were two scenes with old man from the temple telling her that if she can't forget who she is, she can't stay or learn or sth, and in both cases she said that if she wanted to, she could. Noone is perfect - she must fail on something. I believe her training would be partial.
[Ok, maybe it's just because of the fact that I consider her kind of similar to Cirilla/Zireael (a character from some fantasy book that's better not to be read in English - I don't recall hearing about translation being something better than horrible), who as well has learned from a few people at a few places, mixing what she has learned with her own natural "magic" abilities (Arya has wolf dreams).]
At first I suspected that the two swords made from Ice were destined for those two Eddard's children who weren't killed - Arya and Sansa. Well, that was when I didn't believe Bran and Rickon had any chance of surviving. And I wondered what Sansa would do with sword she can't use

. Now my guesses would be Arya and Rickon (Bran being rather unable to fight physically), though I won't risk a bet. With Arya getting Oathbreaker, of course. Ok, maybe she should rename it... mmm... 'Needle' will suit, won't it? XD
Littlefinger - one of "those" characters who know that where neither begging nor threatening works, gold will do. Maybe he'll survive, gaining nothing but experience, leaving for a new game... or we'll see his downfall. I'd love to read his POV, but on the other hand it would be like spoiling half the fun...
Dragons, Rhaegar, Daenerys, all that mystery - the theory I like most is with Jon being Lyanna's son and Aegon (Rhaegar's son) surviving - the only confirmation of his death ever are Mountain's words. There were many speculations as to who could he be... I suppose the most possible is the one with Edrick Dayne, (thought to be?) younger brother of Arthur Dayne (one of the Kingsguard knights who died defending Lyanna in Tower of Joy). He has Targaryen features, purple eyes and silver hair, and told Arya he sometimes sees things in fire. And he was milk brother of Jon Snow, their "mother" being Wylla, girl from Starfall, whose name Ned mentions to Robert - in the other words, everything is ok apart from his age:
"Arya got goosebumps when Lord Beric said her father’s name, but this Ned was only a boy, a fair-haired squire no more than ten or twelve."
Then again, if he was Jon's milk brother he ought to be closer to fourteen than ten or twelve... he might have even been fifteen, as Aegon should be. Arya might have judged him by her own elder brothers, described as tall, and he might have been relatively short or just start growing up rapidly later (which happens). Though would Martin put such an estimation if it was completely wrong? ; ).
Jaime - the last, but not the least... Have you noticed how the irony is exposed in his POVs? Other people's lifes might be harsh, awfull, unlucky, but only he seems to be Fate's toy, from the very beginning when he takes the white cloak, to having to break so many oaths - make so many choices like "betray these or those?", being called Kingslayer with s*** for honor, but having a horse named Honor, calling his sword Oathbreaker in his thoughts, etc. And he pays so much attention to Jeyne Westerling... first time it's mentioned when he thoughts something like "at least she hasn't disappeared", second while talking to her and her mother (making sure she isn't pregnant and that she won't wed too soon, so anyone could have doubts), third while she's leaving - "watch over her, she might be far more dangerous than Tully if she escaped"... Jaime's description of the girl doesn't suit Catelyn's. "Jeyne" is acting as if she's been just told her husband is dead, not some time ago. Blackfish didn't send off Jeyne and her family though they'd been pardoned. He kept the direwolf banner high, and didn't even consider (from others' POVs) leaving Riverrun to Lannisters. Maybe they waited for the baby to be born and wanted to send it off, then pretending Jeyne was never pregnant... but Jaime's intervence changed the situation. Edmure couldn't have known, could he? But then again, they needed someone to play the role of Jeyne... they found some girl, though without much choice, she was neither very similar to ex-queen nor knew enough not to be afraid to talk. Lady Westerling have every right to be distressed, with her pregnant daughter escaping through dangerous land and poor fraud. About her giving contraceptives to her daughter and collaborating with Lannisters - I've understood it otherwise... I think theory "Lord Tywin requested Jeyne to seduce Robb Stark" is a bit too weird. It seems to me that while pardoning Westerlings, Lord Tywin send a message "suggesting" that it would be better for Jeyne not to be pregnant, but Lady Westerling wasn't likely to kill her own daughter's unborn child.
Still think it's crap? Remember (and imagine) the part with Jaime meeting false Arya at Red Keep or wherever it was... She was just leaving, didn't look at him, but at the ground... exactly as "Jeyne" does later, though everyone else behaves normal. I like this detail xD.
Ok, maybe it IS overspeculating. But it is probable, at least

. And why on earth would Martin write and write and write about Jaime's concerns about Jeyne's possible pregnancy?
