Howdy, folks.

Is there any word on what kind of accessibility features the game'll have? I'm mainly interested in subtitles, since I'm hard of hearing, but I'm sure there are other inquirin' minds out there that want to know.

http://www.rockpapershotgun.com/2012/09/03/gaming-for-everyone-game-accessibility-guidelines/ from RockPaperShotgun on accessible gaming should give you a general idea of what features I'm asking about, while also keeping this post from becoming TL;DR.

I'd be shocked if there weren't subtitles. I'm not sure about other accessability settings. I can hear fine, but I always put on subtitles.

This.
Well my hearing isn't perfect but it's good enough to get by.

Nevertheless, there are some instances in games where an explosion or something loud happens while somebody's talking about you can't hear what they say.

Subtitles are good, but I want to feel like a hardcoe assasin, then I will play only with the Piero and Sokolov's bars, without subtitles

Subtitles are a staple nowadays in gaming. I will be shocked if they didn't add such a minor feature, especially when they are adding such detailed options for almost everything in the game.
