I’m suspicious that the article is claiming that Apple plans to introduce this in December.

• A change in behavior and appearance this substantial is generally the type of thing that product managers target for a full number release rather than a point release or new product intro (which you don’t want do in December) . Could be that this was planned for iOS17 and missed the cut.
• Nearly every company puts the restrictions on making substantial network / device / experience changes for a variety of reasons…Including that you often have key resources needed to recover if something goes wrong taking PTO and traveling (not only within the company but at partners as well).
• Apple doesn’t like to push things like App updates separately from OS updates…Pushing an OS update in December would mean that nearly all people who received ATVs as gifts would get the current / old “multiple apps experience” when they initially connected it - which isn’t the impression that Apple or gift givers want to give. It also would change the “buy flow” for content / games which will generate increased support contact on top of increased support contact from new owners

If this is coming (and I hope it is)…I think it will be in 2024.
