User blog comment:Argorrath/Treyarch posts a message of zombies; possibly hinting to a DLC 4/@comment-82.12.192.38-20130803135719

Do you know how much death threats Vonderhaar would get if he didn't bring the old guys back? Everything seems to point towards them returning. It's really not too far-fetched to assume that.

I think they'll have another 5/6 maps in a Black Ops 3 before they think about ending zombies.

Misty/Marlton/Samuel/Russman VS Dempsey/Nikolai/Takeo/Richtofen in Grief would be pretty cool.
