Game of Thrones - S4 predictions (spoilers for the non-book readers)

So I'm too lazy to read through the 12,000+ post mega thread and I figured I would start one to specifically talk about S4.

For the readers of the books and based on where we were left and how long we've had to wait for tWoW, how do you see S4 (and beyond for that matter) playing out? Obviously, there is still quite a bit that was left out of SoS which the previews show they will cover but how far do you think they will go into the last 2 books?

With where they are and just the sheer volume of content available, I can really see D&D barely touching 4/5 and dragging it out over 2 and possibly 3 more seasons to give Martin some time to release the next volume. However, I can also see them losing patience with him and continuing the story on their own. It's been a while since I've read the books so I can't really remember what would make a good stopping point for each season.

ETA: 13,000+ now.
