The locket, the cup, the ring, the snake, the diary, something of Ravenclaw's or Gryffindor's... How many of y'all were muttering that for weeks after HBP was released? Now, two year's later, have you come to any conclusions?
What do you think is the last horcrux?
Here are a few comments from JKR on the subject:
"Harry now knows - well he believe he knows - what he’s facing. Dumbledore's guesses are never very far wide of the mark. I don't want to give too much away here, but Dumbledore says, ‘There are four out there, you've got to get rid of four, and then you go for Voldemort.’ So that's where he is, and that's what he's got to do...Dumbledore has given him some pretty valuable clues and Harry, also, in the course of previous six books has amassed more knowledge than he realizes."

JKR in the Mugglenet/TLC 2005 interviewAmong the fan theories I've heard are: one of the trophies that Ron polished while in detention (possibly Riddle's award for service to the school), the wand in Ollivander's display window, Harry's scar, something belonging to Florean Fortescue, the pillar of storge... oh wait, wrong rumor.
Anyway, what do you think?
