The Battlefield 3 Website has details on Battlefield 3 End Game, a new DLC pack said to be coming to the military first-person shooter sequel (thanks BF3Blog). Word is:

Battlefield 3: End Game delivers some of the most high-speed warfare to date across four vast maps. Race through enemy lines using the new dirt bike, bringing speed and agility to the Battlefield, or fight back aerial assaults with new lightweight AA vehicles. Coordinate lightning fast attacks and defenses in the return of the classic Capture The Flag game mode. In the skies, the new dropship introduces the ability to turn the tide with rapid deployment air drops of troop transports.
