As an aside, I think Apple are at the o wry roast keeping the option of making the “iPhone air” ( NOT the “iPhone 17 air) a limited edition once-off.
Going by my logic, the “iPhone fold” or “iPhone anniversary” won’t be added as an extra phone to the existing line up, they’ll replace the air.
So, the range will be:
Budget ( currently 16e )
normal ( currently 17)
Pro (currently 17 pro)
Big pro (cutrent 17 pro max)
Limited edition ( currently iPhone air)
The range I’d already pretty wide, so they might just change the limited edition every year or two years, rather than widening the range. And they won’t be given numbers.
The plus for Apple is that the “limited editions” don’t need to sell we’ll, and they don’t have to take a public hit fir cancelling, because it’s limited edition to start with : “We’re not cancelling this product because it was always planned to be manufactured and sold only for this period”.
The good news is that it might mean a new mini one year, but it won’t be upgraded with chip bumps unless it’s a huge seller.
