Nature's Oracle finally has a publication date

The W. D. Hamilton biography, Nature's Oracle finally has a publication date. Amazon says March 1st, and other places say April 1st (For the USA). I don't care much either way, I pre-ordered. Now it would be nice if more academic books were available in Kindl format though. I'm not anticipating the "physical pleasure" of have it shipped to me when I could just get it emailed to me on the day of its release.
