I highly doubt they have a detailed roadmap for season 6. They might have a highlevel overview of where they are going, but that's about it.

The details get fleshed out when they actually write the scripts, and every once in awhile, the scripts take on a life of their own, and alter the direction of the story ever so slightly.
