User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-190.51.101.102-20130807220451

I think that they are the old crew, only that they are redesigned. you know black ops went on sale long before than BO2 and maybe they only improved the graphics to make them look better.

And about all the other things in the video, I dont know :P we must wait another trailer.
