yes, the final season is three 8 episode arc's. The comic book goes further than that but AMC decided to end the show. it shocked the producers, actors and etc and they adjusted the final season to have an ending instead of having the story that was supposed to unfold.
Then, AMC decided to announce two new spinoffs, including one a week ago. these spinoffs forecast that certain members will not die in the final season and really suck the suspense out of the show.
AMC is more concerned about marketing their spin offs than keeping the actual show good. the whole point is you do not know who will die on any given episode yet these days, no one really dies and they announce new shows 2 years in advance and who is in the shows so that you know who can not die.
