Actor Iain Glen claims
that the Season 5 scripts have already been written. Makes sense given the nature of the production (i.e. based on geography). That means that Season 6 will be scripted prior to Book 6's release as well. The show is going to have to choose between wheel-spinning, outpacing the books, or even telling its own story.
A want one of the non-wheel-spinning options.
