Ok, now that I borrowed my friends PS3 and with the Steam Sales my backlog will increase A LOT.
PC: Payday The heist (Have to say i'm impressed this is a damn good 4 player-co-op FPS), Orcs Must Die, Super Meat Boy, Assassins Creed Brotherhood and Terraria.
PS3: Yakuza 3, Condemned 2, Virtua Fighter 5, The Darkness and just started Castlevania lords of Shadow.
Temporarily stopped playing: Fo:NV, Deus Ex HR Missing link, TF2 (my usual playing buddies haven't made themselves available), Bastion.
Beated: MK9 (Though I haven't beated the last challenge), Shank.
