User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-1263839-20130807171325

Well, I hope it's a nice ending. Nice to see the old maps. But what the hell was with the robot at the end?

Incoming a load of bollocks speculation, I've already seen about a dozen "THEY'RE A YOUNGER ORIGINAL CREW!!" comments on the video.

Also note the lack of Call of the Dead, "Five" and Dead Ops Arcade on the images.
