I'm sure you're right that the Great Pyramid is about to give up its mysteries. I believe it's greatest mystery is how could highly superstitious people have built it with primitive technology and primitive materials. It will not be so much the pyramid giving up its secrets as it will be the dogged determination of centuries of modern people wresting an actual understanding of its builders from the Great Pyramid. It will be a triumph of the scientific method over our own nature.
Of course I know you don't agree but then we'll just have to see as the results of recent testing finally starts bearing fruit after seeing the light of day. A little water, a little light and almost anything can grow.
