Not really - but the "Lamb of Columbia" trailer is all about her. Well, mostly about vague notions of her untapped power over the world. She's not Jenny Quantum, but that's okay. I just hope that this doesn't mean that the next BioShock game - inevitably to be set on the moon in 60s - won't have to up the stakes with some sort of reality bending hyperspace core. Otherwise, the trailer does not present us with anything that new, but you are free to enjoy it!
