If anyone is still interested in this book, the price on Amazon for the print edition keeps going up. Before the book was released it had originally been priced around $55. It went down as low as $51 before it started creeping back up, and kept going up. By the time the book was released the price was over $60, and as of today it's up to $69, which is not much of a discount on the publisher's price of $75.

The Kindle edition, however, has been lowered from $60 to $43 as of this morning (perhaps to compete with Barnes and Noble's Nook edition).

From the impression I have so far, I would say all editions are quite overpriced.
