1. Heads with skin around the eyes which will deform as the eyes look around - i.e. automatically adding subtle secondary motion to the eyelids and skinned sockets - this greatly increases the realism of face animation.
2. Automatic texture animation for face animation - e.g wrinkling brows, cheeks
3. Animatable colour changes - e.g. 'blush to blue' for characters being to hot or cold
4. Hair styler - create hairstyles which could then be baked into different poly counts
5. Easy limb replacement - select a body part and replace it with a separate imported model
6. Animals - a complete animal creation system - but for animals, rather than people (cool..)
That's it,
Dave
