(NO spoilers, just speculations!)
On spoilthedead.com forum, someone posted extended synopsis for season finale from their cable company:
Description: "Factions begin to near an inevitable collision, which brings Rick face to face with a shocking form of brutality that threatens the lives of everyone he has become responsible for, so the group must find a way to survive the oncoming storm."
So it's kind of extension of synopsis we already had from AMC for "A", but it gives some ideas.
First, we know most (if not all) of the groups will reunite in season finale: "Factions begin to near an inevitable collision", it's quite similar to "Many paths collide" from AMC synopsis.
Then in AMC synopsis we had "Rick faces sheer brutality", here we have "which brings Rick face to face with a shocking form of brutality that threatens the lives of everyone he has become responsible for". I doubted about Hunters appearing this season since the group was so split up and Terminus seemed to be major plot point for this half season, but what can this "shocking form of brutality" possibly mean? Of course cannibalism is answer that comes to mind first. It is certainly shocking, and it certainly threatens the lives. If it's shocking that it can't be simple battle between two groups or whatever, we've seen that already, so it wouldn't be so shocking for sure.
Last part of synopsis: "so the group must find a way to survive the oncoming storm." doesn't really mean much, we already know their lives will be in jeopardy.
What do you think? Does this description make you think that we will in fact see the Hunters this season? Or maybe "shocking form of brutality" is going to be something different?
