I haven't touched the soft body physics yet, but if some kind of gravity effect could be simulated, that would help a lot.  Not only with breast movement, but with big pregnant bellies.  When the woman lays down, the belly as they are now has no way to simulate gravity. 

Internal organs, I seem to remember some being made for V4, I think.  Didn't interest me so I didn't bother.  My thoughts, if it's visible without medical equipment, it should be shown.  If not, then we don't need it.  Well, maybe a 3D Jack the Ripper might.
