I got the exact same email as you (and I ordered exact same model as you). However, checking my status page still has the "estimated" wording. It said my estimated ship range has changed from 9/24-10/3 to 10/9-10/17. Hmm.
My status page on the website states the exact same thing as yours but I was more interested in the wording in the email that made it sound definite instead of estimated. I tried calling the 877# and it still lists it as backordered. To me it sounds like the identified the issue and are working hard to resolve the extended delay in our model. If they didn't send out that apology email I would assume they are just dragging us along but I feel a bit more optimistic now.
