most promising game of thrones theories

as a fan of the phenomenal masterpiece game of thrones, i cant wait to see how it all ends, so instead of waiting like most people, i gathered what i think are the most likely to be true theories.
so here is my list enjoy =)

1- Cersei's death :
well,im sure we all can agree that Cersei is definitely going to die (horribly i hope) its been a dilemma whos going to do it because basically everyone wants to, but without a doubt it must be Jaime and here is why:

What this means: With the death of Tommen, Maggy the Frog’s prediction that all of Cersei’s children will die has come true. However, there’s one more tidbit that concludes the childhood prophecy: Cersei will be killed by her “Valonqar,” or little brother. A lot of people have taken that to mean Tyrion, who’s currently en route with Dany’s army to kick some Westeros ass. However, he’s not Cersei’s only little brother. Jaime, Cersei’s twin, was born a few minutes after her.

The last time we saw Jaime, he was horrified, watching Cersei take the crown. He is clearly not happy with the direction the kingdom and his family are taking. Even though Jaime has said time and time again that Cersei is the most important thing in his life, that may be tested if someone else in his life is threatened, such as Brienne of Tarth, or even the Stark sisters (who he’s sworn to protect). And, given Jaime’s reputation as the Kingslayer, it would be heartbreakingly poetic justice to have Jaime kill the Mad Queen, too. Sure he seems to be standing by Cersei in the new trailer but... things change.

2-Jon Snow is The Prince Who Was Promised:

What it means: Now that we’ve gotten that pesky “R+L=J” theory out of the way, because it’s totally canon now, we get to look further into what that means. The biggest is whether he is the Warrior of Light or Prince Who Was Promised. All signs point to yes. Melisandre’s prophecy states that the Prince Who Was Promised will have the blood of the dragon and will be reborn in smoke and salt (in the books Jon's wounds smoke and his comrades cry salty tears all over him). Whenever she’s looked into the fires for Azor, she’s only seen things to do with snow, which can’t be a coincidence. In addition, Jon picked his Night's Watch post over his lady love (Ygritte), which ties into the original Azor Ahai and Nissa Nissa prophecy.

Interestingly, a less popular fan theory suggests that Ser Davos could be the Prince Who Was Promised. He has been linked to Melisandre throughout the show, and was reborn in smoke and salt when he was pulled from the water during the Battle of the Blackwater. His presence could also explain why Melisandre assumed it was Stannis for five seasons, before he was killed by Brienne. Food for thought.

In season 7 episode 2 Melisandre suggests it could be Daenerys, as she speaks to her about the prophecy. The show makes a point of stating that the High Valyrian term for 'Prince' is non-gender specific, suggesting it could even be Dany herself.

3- Bran is Bran The Builder and (all bran's of the past):

What it means: For those who don’t know, Bran The Builder was the man who created Winterfell and raised The Wall over 8000 years before the events covered in Game of Thrones. There’s belief that our Bran and the former Bran are one and the same person because of his ability to influence the past. We already know Bran can see into the past and future, and he can influence events and 'warg' into people. “Hold the door,” anyone?

If he's aware of the White Walkers in the present day, maybe it's his responsibility to travel into the past and raise The Wall to keep them out. Also, in the books Old Nan mentions - on several occasions - that Bran's favourite stories are the ones about... yup, Bran The Builder. Is that an echo of the young Stark's future? Maybe. But hang on... if Bran builds the wall, but also gets marked by the Night King and allows the Whitewalkers to pass it... ? Does that mean he's wasted his time? Or does it mean he built the wall to hold the undead at bay until man is ready to deal with them.
