I think the horcruxes are:
1)<strike>The Diary</strike>
2)<strike>The Ring</strike>
3)The Locket ((which is at Sirus's house!))
4)The Cup/Goblet thing
5)Probably something of Ravenclaws
6)HARRY'S SCAR

It makes sense!!lolz....but really....i think that harry's scar is a horcrux cause the last word of book 7 is Scar!
