I say HBO is losing patience with Martin. There has been speculation that the show will outrun the material and Martin's series will be ended on tv before he writes the books
I m glad I did not read the books, I am sure it would be driving me crazy watching the show
Anyhow, I think this season is a great deal more watchable than last season, seems a little more coherent.
So I am guessing that whenever it ends, we will see something like these white walkers invading south taking over Westeros despite newly made alliances to defeat them
The Dragon Queen chickie will, by then, finally be coming into Westeros, and she and her Dragons will be the only way to stop the white walkers (since we got a preview in season 1 of how fire is the only way to kill the walkers-I am going with that)
All the other stories in between will add to nothing since the main battle will between fire and ice at the end (of course the fire god witch and her religion may prove helpful as well)
Its my guess and I am sticking to it
Probably have to wait 10 yrs to get an ending though
