The latest gameplay video for Battlefield 3 is out for everyone to lose a pair of underwear over, this one is named "Get that Wire Cut!" and is explained with some text from DICE/EA as:
"Get that Wire Cut!" refers to the fact that Sgt. Black in this episode needs to disarm a bomb. Episode III starts with Sgt. Black crawling through a ventilation shaft, melee fighting an enemy in a basement, disarming a bomb, then exiting onto the streets for a massive shootout with multiple enemies and supporting friendly troops.
