Where are the Horcruxes?

No: HPFGUIDX 133151

Since we have so so so long to wait for the next and final installment of the HP series I 
though we might spend our time hypothesizing where the horcruxes might be (or who 
might be holding on to them...)  We know that Lucius had the diary and that the locket 
should have been in the cave where Tom Riddle visited as a youth (do we know where DD 
got the ring from?  I can't remember now...) but where could the cup, Nagini, the real 
locket and the something else (the scar! you all yell) be?  And how might these locations 
match up with characters we still need answers for?  For  example might wormtail 
unbeknownst to himself be carrying the cup in that weird hideaway at Spinners End?  What 
about the Gaunt's old house?  #12?  I have no answers but I thought I'd see what you all 
had to say!
