Don't be too surprised with the lack of any real substance being shown here though. There really aren't more than a few shots of game footage and a lot of Deadpool's smart assery. It is just an announcement after all. On the plus side it is being helmed by the team who did all of the recent Transformers games. I thought they did a decent job there so I have some high hopes that they will transfer one of my favorite Marvel characters over to a game well.
As of now Deadpool is slated for a 2013 release. You can also check out deadpoolgame.com for further details.
