Just speculation on my part...it would clearly be a twist no one would expect if Dumbledore was in league with Voldemort. Dumbledore knows the prophecy and is always the one who illuminates the tremendous similarities between Harry and Voldemort (especially in Half-Blood prince). He tells Harry that the difference between them is Harry's ability to love, which can prove to be a weakness or a strength in his battle against Voldemort. Now that Harry knows that he needs to eliminate the horcruxes to kill Voldemort maybe Voldemort knows that he must prey on Harry's love to kill him. Harry realizes that this is his potential weakness which is why he breaks it off with Ginny, but we can be assured that if Harry knows it than Voldemort knows it too and maybe Dumbledore is the link.
