The sleuths over on NeoGAF have uncovered a product sheet for Battlefield 3's upcoming End Game content expansion, revealing that the next DLC will mark the return of Capture the Flag and Air Superiority to the franchise, as well as dropships to perform both infantry and vehicle drops (thanks VG247).

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, or engage in massive dog fights in Air Superiority. In the skies, the new dropship introduces the ability to turn the tide with rapid deployment air drops of troop transports.

KEY FEATURES
Four vast and varied maps designed for high-speed combat and action
Three new vehicles including the fast and agile dirt bikes
New dropship provides support to ground troops with vehicle drop capabilities
Return of the classic Capture the Flag and Air Superiority game modes

Battlefield 3: End Game is due on PC, Xbox 360, and PlayStation 3 in March 2013 --likely with a two week headstart on PS3 once again, followed by Battlefield 3: Premium owners on PC and Xbox 360.
