This is just plain obvious. Not sure it'll be part of the '23 lineup; WWDC does not showcase new iPhone hardware features, but they have the hardware ready and miniaturised enough for the headset; if it doesn't make it's way to the Pro iPhones by '24 at the latest I'd be very surprised.

The sports clips and experiences are also not captured by people with headsets standing on the sideline; I'm not sure why a lot of commenters see this as the bleak new future?
