I heard from my editor at Pearson that copies of books pre-ordered on
informit.com are now shipping. Pearson is also sending books to Amazon.
Although Amazon still shows a Dec 31 availability date, they usually update that
once they get stock in their distribution centers.
The ebooks will be available soon on informit, possibly as early as Friday.
Kindle editions on Amazon usually show up a week or so later.
