You can indeed get it at Doyle's site (if you play a ton of hands), but you're not going to get it any sooner than anyone else... or so I've heard. Even if you find playable games there and manage to accumulae the points, the book won't be shipped to you until it's available elsewhere anyway. Me... I'll just wait and pick it up through Amazon, which currently lists a February 1 release date:
$23.07 and free shipping. Yup... consider my copy pre-ordered
