Hello. 6 mo. reader, first time poster here. I am planning on purchasing the 17in. iMac within the month and noticed something interesting on my saved order with the The Apple Store today (I haven't purchased yet, just the saved one). When trying to view my saved order it gave me the following error: "Sorry, invalid order.", "Some of the items in your order are not available.", and "This order cannot be processed because the flagged items are no longer valid." The only flagged item was the Superdrive in the 17in. iMac. I was curious, so I redid my "shopping cart" order. The only difference that I saw was the part number for the Superdrive changed from 065-3010 to 065-3768. I'm not really sure what exactly this means, but I remembered the rumored Superdrive update a week or so ago and thought this could possibly be it. Anyway, just thought I would share. Oh, I also have screenshots of this, if anyone wants me to post them.
