User blog comment:Argorrath/Treyarch releases a BO2 teaser video called "Origins" for DLC 4/@comment-5290320-20130806213301

So far, none of the previous zombie maps on Black Ops 2 have really grabbed me. Hopefully, this one is different and fun and exciting. Or they could cheap out and make a Rezurrection-esque DLC with previous WaW and BO zombie maps.
