Along with that release date, there's some cool new info over at the PlayStation blog - like the new master and pupil system.
"Essentially, you’ll pick a character to be the master and another to be the pupil. By doing this, the pupil gains new skills from the master, as well as higher weapon proficiencies. Of course, with every master-pupil dynamic, the master eventually learns from the student, and in this case that means the master gains some stat boosts! So much knowledge and so much power!"Give it a read, if you're so inclined.
