Richard Dawkins' The God Delusion will be coming out in October. It's being published by Houghton Mifflin.
However, I just checked Amazon UK and it seems that not only do they have the above but also another version that's going to be released by Bantam a month earlier.
So why may I ask is The God Delusion coming out in two flavors at the same? Both are hardcovers. But the one by Houghton is 288 pages long, the Bantam edition, 372. What could possibly be included in the latter that isn't in the former, making it balloon by 30%? Or is that the Bantam edition is printed in a font size for the visually impaired?
