UPDATE: Ebook available now, in all formats! Print version still won't come out until approx. March 2013, but you can pre-order.
The ebook version will be for sale via early release very soon (hopefully within a week or so). Note that the content is still unedited and quite rough, so that's what you'll get. But of course when you buy the ebook from O'Reilly, you get lifetime updates, including of course a copy of the "final" ebook once all the editing is done, around March 2013.
Currently, only the printed, paper edition is available for pre-order. Meaning, if you click the pre-order link now, you will get a paper copy, but not until March (or so).

For the ebook, just hold on a few more days.
Thanks for your interest!
