Ambience sound features such as 3D sound and a lot, if not all sounds have already been made. There will be plenty of new music pieces, one for every situation, and there will even be footsteps when you run around. Not simply a \"I\'m walking with highheeled shoes all the time\" footstep sound, no it\'s diffrent sounds when you\'re running on sand and so on. There will also be birds like you said, and water sounds, and so on.

So I can easily say there will be plenty of new features in the sound area of CB, compared to what is in MB.
