So I suppose that the temporary relief that Rick the survivors will have in Alexandria is a spoiler, and there have been some others that are mostly rumors, based on what we know from the storyline in the graphic novel series.
For example, we know that Glenn (Stephen Yeun) is going to die at the hands of a villainous man named of Negan, as this is what the graphic novel series has shown in black-and-white (literally, because the comic book source material is in black and white). It is unknown whether Glenn will die in this season, and if he will die at the hands of Negan.
Season 5 ended on strange note. As you may recall, Rick (Andrew Lincoln) shot crazed husband Pete (Corey Brill) in the head, and then Morgan (Lennie James) made his expected return.
The Latino Post says that Morgan's return as well as the arrival of the Wolves, a sadistic group of survivors who could be the main antagonists for the next season, are the scenarios fans should watch out for. There is also a possibility of a romance between Rick and Jessie (Alexandra Breckenridge), even though Rick just murdered the father of her children.
Oh, and another thing could be more zombies. The show has lately focused on humans as the main villains, but Season 6 might remind us why Rick and his gang are together in the first place. Considering that in the graphic novels, the Alexandria safe zone was invaded by a zombie horde, then it would be not surprising if history repeated itself.
Season 6 of The Walking Dead will begin on AMC on either October 11 or October 18, 2015. I realize that for some of you, that might be a long wait, but the spinoff series, Fear the Walking Dead, should be out this summer.
