Because I am a kind soul, here it is embedded:
According the the secret message in the trailer, the game itself isn't actually expected to be released till around 2015ish and will be a completely open world narrative heavy rpg set in the Cyperpunk roleplaying setting. An in-game trailer is in the works.
Within the setting cybernetic enhancements are commonplace, however abuse of such enhancements can lead to insanity which is what the trailer depicts. Said people who abuse cybernics are called psycho's, and tend to go on rampage killing fleshy meat things till they are stopped either by the police, or by a special unit called the psycho squad. That squad in particular known for its habit of capturing psycho and brainwashing them into new members, thus the girl at the end now as part of the squad. It does however erase their personality and make them more machine than human, so don't expect to play one.
And that's that. There's also a snippet about Witcher 3, but that's for another topic.
