Mine still states Nov 3 - 5. I think Apple overstates its delivery times but honestly, anything could happen.
Last year, my M1 MBP w/ 16GB RAM showed Nov. 24 - 27 for delivery (ordered on Nov 10th after the announcement), and it ended up shipping way earlier (Nov 14th, Saturday) and delivered on release day. (Nov. 17th, Tuesday). Considering the release date is October 26th, which is also a Tuesday compared to last year, those with October 26th dates should expect to see preparing for shipment/shipping in the next 2 days.
