I wonder if this is the first year that we’ll see iOS 18 for new devices only?

TLDR: If Apple attempts to launch iOS 18 with a ‘transformer Siri’ on a range of older devices in September, it’ll likely be a buggy disaster.

So perhaps we’ll see:

- New iPhones get iOS 18 with the ‘ambitious’ transformer AI / Siri stuff (which is obviously what this is).

- With older devices on iOS 17 getting new features that aren’t dependent on this.

AND/OR

- A staggered release, with iOS 18 gradually being made available for older devices as it becomes more optimised and stable.

You could imagine them doing the same for iPadOS and macOS too & for macOS, making the next version Mx processor only.
