early Martin is one of my favorite authors, lately his books have gone down the path Robert Jordan mastered. The books are getting longer and longer and getting filled with insignificant details while the story is limping along almost forgotten.
It was originally intended to be a trilogy, but GRRM has always been pretty honest about how he's been having trouble fitting what he's wanted to write into his books without making them huge doorstops. The latest book, Feast for Crows, was originally supposed to have a long prologue chapter that spanned around 10-ish years of time, and he spent over a year writing it that way before admitting it wouldn't work out. So he scrapped that and decided to just tell the story instead in two books: Feast for Crows, and the upcoming A Dance With Dragons (he's not far from finishing it).
Basically it was originally going to be a 3 books series, then 5, and now 7.
Although I've not read WoT, the overwhelming impression I get from people who have is that what GRRM is doing by expanding his books, is not nearly the same as Jordan did: essentially milking his own franchise. But like I say, not read them myself.
On the bright side, book 5 should be finished by the time the series airs next year, and although books 4 and 5 will probably be combined in to one season (if the show gets that far) as they covor the same timeline, it still gives him plenty of time to finish the other 2 books before the seriers catches up to him (if it goes more than one season that is).
