If we have faith in Rowling's ability to put out a decent book, the following can not be true:
1. Harry is a horcrux
2. Snape is still a good guy
3. Dumbeldore is still alive
4. Anyone Harry knows is a horcrux
1+4: These can't be true because we know (well, we can reasonably assume) that in the 4th book, Voldemort was trying to use the muder of Harry to split his soul for the final time. To make a horcrux, one has to murder somebody, to split their own soul so they can hide half in an object. That is what he was trying to do, use Harry's murder to make the horcrux, not trying to use Harry as a horcrux, that would be stupid as he tried to get Dumbeldore to kill Harry in book five. Also, Snape can control Nagini (his snake, however you spell it) because she is a horcrux. Thus if anyone Harry knew was a horcrux there would have been noticable effects from that already. Not to mention Voldemort not ever being too close to them.
2+3: Not happening. 3 is completely impossible. If Snape hadn't killed Dumbeldore then Snape himself would have died due to the unbreakable vow or whatever. 2 would just be stupid. A huge part of the last two books was that Dumbeldore's greatest weakness was that he was too trusting. Greek tragedy! A hero is always killed because he has one fatal character flaw. Dumbeldore is dead because Snape actually is bad.

1. The Diary
2. The Ring (TO RULE THEM ALL)
3. Slytherin's Locket (already destroyed by REGULUS ANDROMEDA [yes. twist!] BLACK. He's now posing as a death eater, a new one, using some sort of polyjuice potion/spell or whatever, a REALLY powerful one. The locket could also be at 12 Grimmauld Place... they mentioned a locket nobody could open.)
4. Hufflepuff's dealie
5. Ravenclaw's dealie (not discovered yet)
6. Either Nagini or Fawkes (Zomg plot twist! How the frizzle do you kill Fawkes?! Also, Fawkes flew away so now what!?)
7. Voldemort himself
We have a winner. There are six horcruxes, which split Voldemort's soul into seven pieces, since he had to keep a part in his body. I'm pretty sure Dumbeldore said that he was pretty sure that Nagini was one in the sixth book. That leaves the thing belonging to Hufflepuff and the thing belonging to Ravenclaw, and the locket, which is probably the locket in Grimmauld place as they painted the Black family as being half-Death Eater and half-good guys.
