I get the feeling that GRRM's vision of the ending has changed several times since they started plotting out the series. The concern I have until the Winds of Winter is released, is whether it will stay a TV series based on a book or become a set of books inspired by a TV series.
Considering he is going to waste time creating a book about his favorite sayings and quotes of Tyrion, I don't have much faith in Martin delivering a high quality ending.
