The Guardian Unlimited had this story about the next Harry Potter book.

Harry Potter’s arch enemy, Lord Voldemort, is odds-on favourite to kill
off the boy wizard in the final instalment of the series. Bookmaker
William Hill said punters were throwing their weight behind Voldemort,
and even Harry, to bring about his demise. The revelation came days
after JK Rowling’s seventh book was revealed as Harry Potter and the
Deathly Hallows. A William Hill spokesman said: "… the general
consensus seems to be that Harry is the final Horcrux and to ensure
that Voldemort dies he will need to be sacrificed." A Horcrux holds a
person’s soul, ensuring immortality.
