For the first printing, the book comes in a cereal box. Brilliant. Limit supply while you pump up demand. Incentivize the early adopters/purchasers with limited edition packaging and get the point of your book across all in one fell swoop.
Even the pre-launch is well done. The book is not out until May, but already we can read a quick piece in The Wall Street Journal and a mysterious blog entry with a .pdf file you can download to learn more about the book. This of course incites other blogs to write about it. I can hear the buzz building.
