MW3 August DLC for Xbox

Release date:  August 7

August DLC for PS3 info - Release date: August 16 (PS3 general and PC will get Terminal August 17th)

The calendar says:

I was so sure they would use the Kill Switch and Arctic Recon maps again for these two missions, but I was wrong.  They have two entirely new missions, Special Delivery and Light 'Em Up.  Official info has been released with a couple of screenshots:

Light 'Em Up (from the campaign mission Stronghold)

Special Delivery (another map not from the campaign)

This is a screenshot from Gamecheat13, not officially released.

UPDATE: Gamecheat13 put video up of Light 'Em Up, one of the spec ops missions: http://www.youtube.com/watch?v=v7E0C_jR3W4

OFFICIAL UPDATE:   Activision has let out the info on the rest of the DLC season.  They are re-organizing the last few drops into two content collections:

Content Collection #3:
Chaos Pack will consist of four Special Ops missions, 3 Face Off maps, and the new Survival Chaos mode, up for general purchase August 9th.

Missions:

• Arctic Recon
• Vertigo
• Special Delivery
• Light 'Em Up

Face Off maps:

• Vortex
• U-Turn
• Intersection

Special Ops Chaos Mode delivers a frenetic form of combat that demands players to outlast waves of enemies, while chaining kills on maps littered in power-ups to achieve the highest possible score:

• Resistance
• Village
• Underground
• Dome

Great picture for Chaos mode:

Content Collection #4:

Final Assault is a classic map pack and will consist of five multiplayer maps up for general purchase September 6th.

• Off Shore
• Decommission
• Parish
• Gulch
• Boardwalk
