I'm certain it's going to wrap up at the same point that book 5/6 ends up. Same last scene with Cersi. Same last scene with Jon. Same last scene with Daenerys. I also expect something similar with Theon. With Ayra, I expect it'll be pretty far off from the books.
Nailed it. Only thing that was way different was Stannis. I guess I know what to look forward to in book 6.
