It will be interesting to see how it goes. I do not think Season 3 is going to finish book 3 as they are adding in other parts of the story (while leaving out huge parts/theories/background info). As such season 4 will be much like this one parts of 3 and 4 mishmashed. Then they will do 5.
But yes, he needs to finish the book already. Huh, this is getting to be a trend in what I say
