I would be very surprised if this is true. New orders are getting estimated delivery dates of just over 4 weeks from now. Apple must be using very conservative shipping estimates then, in an attempt not to have to push any of them back. Better to get the product shipped before the estimated delivery date than after. Makes the customer much happier. For example, if the iMac shipped Sept. 15 when you had an estimated date of Oct. 1, you would be thrilled, but if those dates were switched you would be pretty upset.
Anyways, I'll believe it when you post screen shots of your order tracking, and pictures of your new iMac. Until then, I'll remain skeptical, so as to not get my hopes up about my iMac shipping early too. Nothing personal BigEvan23, this is purely for my own sanity.
