There is one major hole in the theory that Dumbledore and Snape had pre-arranged Snape's killing of Dumbledore. Surely Dumbledore would know what affect that situation would have on Harry? Surely he would know that as much as Harry already despises Snape, he'd be out for some serious revenge after he saw Snape kill Dumbledore?
So now Harry is running loose looking not only for Voldemort but for Snape as well. Wouldn't Dumbledore want not only for Harry to focus *all* of his energy on finding Voldemort but also to spare Snape the possibility of being killed by a revenge-spewing Harry?
Perhaps Dumbleore has left behind a letter or something to let Harry know that Snape is not really the bad guy so Harry won't go after him.
