Ginger:

<<I think there should be 3 left.  One of the 4 that was left is now 
in LV's new body.  We know it isn't the locket, because that was 
emptied by someone other than LV.  We know it ins't Nagini because 
that one was made after his re-bodiment.  So that leaves the cup and 
Rowena's object, one of which should now be empty, having provided 
the new soul for his current body.>>

OK, I'm going to try this again, because after sleeping on it, I 
found a flaw with my original hypothesis.  Which is - according to 
what Dumbledore tells Harry in Ch. 23, it seems as if, once 
Voldemort made the sixth Horcrux (Nagini), he wasn't able to make 
any more.  I'm not sure why, exactly - perhaps Voldemort was afraid 
if he pushed it any further, the piece of soul still left in his 
body would become so small he might wind up dying as a result.

So, following this "logic," the current status of the Horcruxes are:

1. Riddle's Diary (destroyed) - btw, this was likely the "big clue" 
in CoS that JKR was fearful would reveal more than she intended at 
the time
2. Marvolo's Ring (destroyed)
3. Slytherin's Locket (I'm not entirely convinced this is destroyed; 
I don't know for sure whether RAB is Regulus Black; I think it has 
to be someone who is still alive that Harry can check with and 
confirm whether or not that Horcrux has actually been disabled or we 
have to be provided with some proof that Regulus disabled it - 
perhaps he died in the effort?)
4. Hufflepuff's Cup (yet to be found)
5. Nagini (still alive)
6. Something belonging to either Gryffindor or Ravenclaw
7. Ginger - the answer to your question (that I didn't answer 
correctly yesterday) - the piece that still lives inside Voldemort's 
body (see Dumbledore's comments in US version, p. 503, Chapter 
23:  "But firstly, no, Harry, not seven Horcruxes:  six.  The 
seventh part of his soul, however maimed, resides inside his 
regenerated body.  That was the part of him that lived a spectral 
existence for so many years during his exile; without that, he has 
no self at all.  That seventh piece of soul will be the last that 
anybody wishing to kill Voldemort must attack - the piece that lives 
in his body.").  So this means that Voldemort didn't lose the piece 
of his soul that was in his body when the AK backfired, and 
therefore didn't have to replace it with one of the other Horcruxes.

After thinking about it some more, I don't think the piece of soul 
that's in a Horcrux actually moves from the Horcrux back into 
Voldemort.  I think the existence of a Horcrux outside the body 
enables the piece of soul still within the body to exist, regardless 
of the harm inflicted upon the body.  Once no more Horcruxes exist 
outside the body, however, the soul inside the body is on its own 
and the person becomes mortal again.
