Awwwyeeeeah! Mine (ordered Aug.31) was supposed to ship Sept.20th, arrival Sept.22... but I just got an email saying it shipped and I'm getting it probably this Thursday!
UPDATE:
After 4+ hour delay, I finally got my Kindle 3 today, Wednesday Sept. 15th. The 4 hours was because UPS delivered it to the wrong house, and we couldn't track it down till later.
