The book was originally set to arrive in 2012, but this month its release was bumped up to Nov. 21, 2011
That's ominous.
Possibly not. 2012 is only ~5 weeks from the Nov 21 date, and there might be a marketing benefit in releasing the book closer to the release date of the iPhone.
Good point, and I'd much rather believe that this is the reason than something more dire.
