A post to the Eidos Forums by programmer Jim Offerman says that the ability to adjust the field of view will be present in the windows edition of Deus Ex: Human Revolution, the upcoming action/RPG prequel. A previous statement said the ability to adjust FOV would not be included, so this represents a change in plans. The new post is extremely short, simply saying: "I just wanted to let you know: we've recently added an in-game FOV setting to the DXHR PC!" Thanks Shacknews.
