I actually never saw the video trailer but in the game even I'm curious about the blacked out character icons. As for compasses I haven't heard anything about that in-game just yet.
Now that you mention compasses though, I've always been curious about the pendant's design in Walter's picture. Reminded me of a compass the first time I looked at it. Don't be sorry about saying too much either. We all enjoy the game and I just learned something interesting. After all, I didn't know about the compasses until now.
