Yup next season will definitely include new content for Bran, since we know he meets Leaf and Bloodraven this season. Unforunately for readers, Bran's story seems like it's on the closest edge of massive spoilers. Not just stuff like Jojen's fate (ie did Bran really eat him in that last chapter), but visions of the past as well as more concrete info on the Others. I'd imagine we won't see too many visions in the show, as the show runners seem intent on avoiding shyt like that. However clearly they're more than willing to dive into the Others' lore and information. We could learn some major shyt.
TWOW seems like it'll be out next year but at the earliest it'll be out in summer 2015. Next season will start in April meaning we would be spoiled before the book comes out.
We'll see. I'll watch S5 regardless. I think TWOW is gonna be very similar to ASOS brehs, nonstop shyt hitting the fan. Just based off the spoiler chapters it's gonna be crazy, and I think we'll get some major reveals. Which is why it needs to come out next year - if it doesn't, the show will have to reveal that stuff.
we was just talkin about this shyt all week! im not gon lie when i saw that shyt i was 
for a second
told yall dude was down for the cause 
now that we know he saw that shyt all the way back then it just makes him even more of a tragic hero
i forgot he's a book reader
what an a$$hole
