This will be fun. It's Batman in an open world working on a very similar engine to Arkham City, it can't be bad. That said, nothing in this trailer looks very novel or inspired. To me it just looks like Arkham City.....but bigger. Hopefully there will be some big surprised in terms of gameplay and mission types.
The new addition to Detective Mode is very interesting. A much more deductive way to find evidence and clues in a crime scene. The martial artist enemy is cool as well. It's something the game could have used. Although there's nothing revolutionary, Origins does look pretty good I have to say. Baker makes a good Joker but I have yet to be sold on Ezio playing Batman.
