Here’s my guess:
October 13: iPhone 12 series, AirPods studio, AirTags. The new iPhones will ship with iOS 14.1.
November 10: New 16 inch MacBook Pro with 10th GEN Intel processors, new 13 inch MacBook Pro with Apple processors, New cheaper Apple TV to replace the HD with an A12Z processor, new more expensive Apple TV to replace the 4K with the A14X processor, new remote, new HomePod mini, and the one more thing will be a super thin, ultra portable, mega long battery life 12 inch ARM MacBook.
Also on November 10, Big Sur will release, along with iOS 14.2, tvOS 14.2, watchOS 7.1, and the new HomePod update that everyone has been waiting for. Also, Apple 1 and Apple fitness plus will launch with these new updates.
A good indicator that Big Sur and new max will not be announced at next weeks event is that Big Sur is not in GM yet, and all of the 14.2 updates are still several builds away from being finished.
