The date has been moved up and the cover has been set.
Steve Jobs by Walter Isaacson will be out on November 21, 2011.
In an email to Philip Elmer-DeWitt, Isaacson writes:
The cover is the Albert Watson portrait taken for Fortune in 2009. The back is a Norman Seeff portrait of him in the lotus position holding the original Macintosh, which ran in Rolling Stone in January 1984. The title font is Helvetica. It will look as you see it, with no words on the back cover.
