Just wondering if we know anything about how it's implemented yet? I'm hoping that light, cover and sound will have a major impact on your stealth. In past games it seemed to work well at lower levels but by high levels you could basically sneak around in front of someone's face. It's kind of nice because you can steal everything but then again sometimes you feel like it's a bit too overpowered. I have no idea how over/under powered I'd actually like it to be or what it should be though. I doubt I'd like it if it was completely realistic. "ha, ha, I see you.. you're dead now!"
I also wonder how it will work with perks and how much they'll impact how stealthy you'll be. In the past perks like Ghost would add a percent value to your overall skill. But if we don't have an overall skill number..???
