Just finished the video that ZacD posted. While I agree that this is an issue, the points made by the devs seem reasonable and it might be possible that we could see issues like floating hands/etc. with increased FOV. The fact that the hack makes everything squished (even though you can see a bit more) kind of discredits his claim that implementing higher FOV would be easy. He sounds like developers are chosing to ignore those complaints, though personally I do believe that most people are simply not aware of how many gamers are affected by this. Personally, I experience some discomfort when playing games with low FOV even on TV. So I would assume this may affect an even larger share of gamers than just PC users.
On a side note, I think the main problem with The Darkness 2, judging from the video is not the FOV. The guns take up a lot of space on the screen and then when you add the constantly moving demon arms my head just goes bonkers. To give you an idea of what I'm talking about, hold two of your fingers right in front of your eyes and look at something else. Now imagine you are playing a game like this. It's not as severe of course and there's no blurry vision, but you should get the idea of what it feels like.
Playing a game like this for longer than 15 minutes will make your head explode
