I preordered it a couple of months ago from Amazon.co.uk. I just checked, expected delivery date is THE END OF SEPTEMBER. Others are reading it now. In England.
I don't think I'm going to bother preordering from Amazon any more....
I know... it ticked me off that Barnes & Noble was distributing it 5 days before Amazon claimed it was even being released!
I ordered mine 8/3, and its earliest delivery date is 9/4-9/10.
