User blog comment:Werthead/Official: producers will not wait for Martin to finish the books/@comment-250644-20130403180836

I don't mind so much if this scenario happens as long as Martin is certain of the main plot points by the time they want to plough on without waiting for the books. However, as other people have pointed out, this wouldn't happen for a few seasons anyway, and by that time I think most of the young actors would probably be at an age where another year or two won't actually be that noticeable (compared to for e.g. Isaac Hempstead-Wright's change between seasons 2 and 3) so a reasonable hiatus wouldn't actually be unworkable.
