Harry Potter and the Deathly Hallows?

OMG! I can not wait for the seventh book, what do you think will happen? I think Fawkes is Dumbledores horcrux, ('horcruxes are not evil, its the killing that is done to make them' - slughorn) because on Dumbledores chocolate frog card, it says Dumbledore is known for his work with flamel and for his takedown of the evil wizard gairloch (or whatever), so maybe dumbledore had to kill gairloch and the opportunity to make a horcrux just happen to come with it? I think fawkes because a phoinex can not die and that would be perfect, I also believe Hagrid may be the secret keeper that fawkes is a horcrux because in SS he(Dumbledore) says " I would trust hagrid with my life" and also dumbledore suspects Voldemort would use his pet nigini, why eles would he think that if he himself had not done that.Also I think Pettigrew will save Harrys life because Harry saved pettigrews life in POA, and when a wizard saves another wizards life theres is a bond between them and the savie has a debt to the..
