The Deathly Hallows, I think many believe, are the horcruxes. We know that the diary and Gaunt's ring are already destroyed. The locket may or may not be destroyed, and there is the piece of soul in Voldie. Which leaves 4 horcruxes. I think Dumbledore was right about Hufflepuff's cup, and I think it has been said that the sorting hat and sword are the only remaining posessions of Gryffindor's (and those are safely in Dumbledore's office). Which leaves something of Ravenclaw's and, possibly, Nagini. While many thing Harry is a horcrux, I do not believe so.
Isn't it weird that in only a day we will know EVERYTHING! Hopefully I find some time tomorrow to write my last Pensieve in the book 7-less world of HP!
