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

OK, let's drop the cow on some of the speculation:


 * 1) Just because the entries are dated 1917 does not mean the theoretical map is going to be set then; it could just be backstory for it.
 * 2) No mention is made of any names; this could easily be a map featuring the BOII cast, or it could be another entirely new cast.
