So it looks like that John Prosser was right, and 14.3 will be out with the airtags. Here’s my prediction:
November 2 or November 4: iOS 14.2, tvOS 14.2, watchOS 7.1, and HomePod OS 14.2 are all released to the public.
November 10: Apple announces event for November 17, and also releases Big Sur 11.0 GM.
November 16: HomePod mini ships running iOS 14.2.
November 17: apple ships new 16 inch Intel MacBook Pro running 11.0.
Mid December: Apple releases iOS 14.3, tvOS 14.3, watchOS 7.2, and Big Sur 11.0.1 to the public.
Also mid December: Apple releases 12 inch Apple silicon powered MacBook running 11.0.1, air tags which require 14.3, and the leather sleeve, smart battery case, and magSafe duo.
