Treyarch and Activision just announced that the First Strike DLC Map Pack will be available on the Playstation 3 starting March 3rd, 2011.  The content includes Ascension, a continuation of the Zombie takeover, as well as four additional maps with Berlin Wall, Discovery, Stadium, and Kowloon.  The content has already launched for the Xbox 360, and with just under a month left until PS3 owners can get their hands on the DLC, it will be nice for current owners of the game to get some new maps that can reinvigorate the already booming interest in the game.
