You're welcome
I doubt she'll be bringing back Dumbledore at all, and I'd rather she not. Much as I loved Dumbledore, I really dont like 'cop out' deaths, where the death is used for emotional purposes and then just undone to make everyone happy again.
I knew they were going to kill Dumbledore off quite a few books back, what with all the mentionings of Dumbledore being the only wizard Voldemort feared, and things like "As long as Dumbledore's here you're safe, Harry." So to facilitate the neccesary death match between Voledmort and Harry, Dumbledore had to be out of the way.
