The trailer hints at a major event from the comic books.

AMC has presented its first look at The Walking Dead Season 8. The extended trailer debuted at San Diego Comic-Con, and it features the unification of the Hilltop, Alexandria and The Kingdom, all to take on Negan and his band of Saviors. It also seems that the group will stick together for a majority of the season instead of them being separated like seasons prior. The trailer also makes sure to display a gaggle of walkers just in case you’ve forgotten the threat of the undead.

The end of the trailer features a cane and a gray-haired Rick in bed, hinting at a major event in the comic books that may seemingly happen in the show.
