The BioWare Social Network has word that Mass Effect 2 owners who also own the Cerberus Network will be getting more free DLC tomorrow at around noon MST, which is 2:00 pm EST (thanks Kotaku). The Mass Effect Website has images of the new Cerberus Assault Armor and M-22a Eviscerator Shotgun, described below.

Cerberus Assault Armor
Cerberus assault armor is designed for shock troops, turn the tide of battle against creatures or forces that would decimate normal soldiers.
Increases heavy weapon ammo capacity by +10%
Increases shields by +10%
Increases health by +10%

M-22a Eviscerator Shotgun
The M-22a Eviscerator Shotgun is a longer-range shotgun with armor-piercing loads. This design also violates several intergalactic weapons treaties, so the M-22a is not distributed to militaries.
