That's according to Infinity Ward executive producer Mark Rubin, who also confirmed on Twitter: "Details on the content will be posted on 6/18."
All we currently know is players will gain access to three pieces of content - a new map, a new mission, and another "classified" download.
Content drops 13, 14 and 15 will form the first pieces of content set to be included in the third traditional Modern Warfare 3 DLC collection.
Last month's MW3 DLC for Xbox 360 featured four maps specifically designed for a new multiplayer game mode called Face Off, which offers 1 vs. 1, 2 vs. 2 and 3 vs. 3 close combat gameplay. It's due to hit PS3 this week.
