I adore the books and have always read the books with my "movie mind"... yet, the expense of bringing these books to the TV screen - I just don't see this lasting 6 to 7 series. Two possibly, which would leave the show on a big, epic finale but no conclusion.
Given Rome/Carnivale/Deadwood's experience with huge budgets Game... seems unlikely to last.
Yet, to see a truely adult, rich, textured and thematically grown-up fantasy series on TV would blow my mind - especially with this kind of pedigree, and with HBO behind it.
We shall see and cross fingers until they snap because, like the books, this could be legendary.
