User blog comment:Argorrath/Treyarch posts a message of zombies; possibly hinting to a DLC 4/@comment-356904-20130731230558/@comment-3967954-20130801133951

The Green Run crew won't be dead. Richotfen is controlling Samuel's body (providing you did the Richtofen side of the EE) so they wouldn't kill him off. And there's absoloutely nothing to say that they're dead.
