Don't count on that. I ordered a 64gb 11 Pro Max about 1am this morning and the rep on the phone said it would be shipped this Friday or Saturday but I just received a text message saying it would ship out between October 9-25. I would tend to believe this since it's said these dates on their website since Saturday I believe.
My text says 9/21-9/24, which is what the website said before and after I ordered. I think it helps that the 64 GB is probably one of the less popular models for pre-order. We'll see, though. It's not like I NEED it right away so if the date slips, oh well.
