cue harry potter theme

i went out for thai food last night to discuss possible theories for the next harry potter book, and this is what we came up with.
1) harry is actually a horcrux and will have to be killed think about it and it will make SO much sense
2) snape is not evil but since the unbreakable curse was put on him he had to kill dubledore, and dumbledore sacrificed himself for the order
3) sirius' brother and or grandfather is the one who has the locket hence it is in harrys possession because he inherited it
4) harry will discover dumbledores memories through a pensieve etc
