Take for example, the fact that many have complained about the animations of things in past games, and how with the new Havoc Behavior part of the Creation engine, it could very well improve that. Also, I remember for those of us who what the stealth system greatly looked at, there was a whiteboard during Todd's video tour that seemed to focus on stealth. There are quite a few other exmples as well already from what I've seen: camera will no longer zoom to peoples faces, realistic branch movement and snowfall, etc...
Now I realize this so far has been just words, and we are real early into the information release, until we actually play the game we won't be able to know for sure, after all things could get cut before the release (HOPE NOT!), but I already feel that they have been paying attention to us, even though some others might say otherwise. Do you agree? What else have you noticed that you wanted changed/added/improved that looks to be fulfilled in the information on the game we've already received?
