    * Bullet SDK support (for 3D Physics)
    * Audio engine with OpenAL support
    * Networking with the ENet library

Planned features:

    * new sound engine
    * a few new file formats that make the art workflow smoother
    * a Super Monkey Ball kind of camera system
    * a new model and scene format like the .x file format or the DOOM III formats
