Just went to take a look at my order (11/24) and initially the shipping date was still stuck at "shipping after the 25th". I toyed with the idea of changing to 1 day shipping (w/ my free Prime trial), but after opening the edit shipping page opted not to. After returning to the order summary however my shipment has now shifted to an estimated deliver date of 12/7!
This seems to be in line with phase315's experience (looking back through posts it looks like their order was a few days before mine and now get the same date after actually changing shipping), so I wonder if those of us seeing the dreaded "after the 25th" line are seeing a generic cached page from Amazon, and modifying your order in anyway (or even just clicking the edit shipping button) is forcing a refresh on the main order page.
Now the real question is if this new shipping date has any real implications, or if this is just another placeholder.
Tried that, still says after December 25th. I ordered 11/20, and my card still hasn't been charged.
Thanks, clicking on "Change" for the Shipping Speed resulted in an update to the "Shipping estimate" date. The "shipping after Dec 25th" message was replaced by 12/4/09 and a "delivery estimate: December 9, 2009 - December 10, 2009" now shows in "When will your items arrive".
