Albus Dumbledore must die.

 MadameSSnape (Sherrie)wrote:
I think Albus, once gone, will be gone, except as people invoke the 
wisdom within themselves that they've learned from him. The only way 
I MIGHT see him making a "guest appearance" is if we were to discover 
that good old Sybill's true talent is as a trance channel.

Arya now:
Dumbledore's death would not surprise me in the least.  However, I 
think we can safely assume he will indeed always be around in a way--
as a portrait.  Every Hogwarts Headmaster has a portrait.  As one of 
the greatest Wizards of the age, he's likely to perhaps have even 
more than one out and about the WW.  We shall surely see him in this 
way and I'll bet he's painted with a tin of lemon sherbets, too.
