From what I saw of the trailer, I think he is probably a nerdy teenager with a god complex personality. From what the trailer have shown, I think this guy will start a movement or from the outside perspective of the inner circles of Kira and Zero, a cult perhaps.

There was the leaked trailer.

So far, it plays in San Francisco and takes the Sand Andreas Gangster approach.
Parkour could be also a new gameplay element. Underground parties with people who have horses on their heads.. wtf is wrong with these people... nevermind...
looks interesting for me.

We'll see.

The problem of the first WD protagonist was that he wasn't a good person to begin with so it's hard to relate with a criminal that had no redeeming qualities. I hope Ubisoft fix that with their next game.
