Is Dumbledore dead?

Ok, a lot of websites talk about this and let me pitch in my views on this:

1) I feel Snape is surely a good guy. No need to point out the evidence. Only a dumb idiot would miss the fact that in every book she tries to make him the bad guy and finally he turns out inculpable. Moreover, plenty of evidence in book six to suggest that he is indeed a good guy, such as "Dont call me a coward" scene, Dumbledore pleading Snape to "do the job" when he says "Snape, please"....come on, a man like Dumbledore would never plead for his life, and if he was not pleading for his life, then it was something more and if it is really something more then Snape is a good guy.

2) Secondly, JK has supposedly informed her fans that Dumbledore is defly dead (in an interview as an answer to Salman Rushdie). Here I have a new angle,

Consider this:

IF you are JKR, and you are asked :

"Is Dumbledore dead?"

You can say:

1) No. He is not dead.
--> And therefore give away a lot, and a lot of readers, though happy, would feel "what nonsense, why did she reveal the suspense"

2) No Comments.

--> In which case it become obvious without you telling....that Dumbly is not dead.

3) Yes he is dead.

--> The safest route. You have to stick on to what you have thus far said so that people shut up and stop asking more questions. Tomorrow, even if you wake him up from the dead, nobody is going to complain. And on top of it, as far as Book 6 is concerned he is dead. So he is dead. Full Stop. So JKR is not really lying anything.

Considering the three options, JKR has only used the best viable option, and I still tend to think Dumbly is not dead :)....I will give a 80:20 chance for his survival (or rather some sort of a comeback). A 100:0 chance for snape being the good guy. And if it really turns out Dumbly is dead, he sure has done a lot more (perhaps kicked out a few more horcruxes, taken care of a couple-a death eaters etc, without informing Harry, and also has arranged for a lot of other things which may unravel later) than what has been mentioned thus far.

Eagerly awaiting book 7 with Rs.1000 and for movie 5 with Rs. 100 in my hand :)
