Apple’s September lineup is shaping up to be a lot more than just a new iPhone. A foldable Ultra, AirPods with cameras, and a HomePad with a screen all in one event would be a lot to take in at once. I have already mentioned these potential Apple devices earlier. And while 9to5Mac lumps all of them (pro-sumer and consumer tracks) together, and some of these are “wildcards” as 9to5Mac mentions, I’m pretty sure the iPhone Ultra will be the champion of the announcements.
That being said, iPhone Pro models will definitely be coming. I always recommend getting a new iPhone every other year if it fits in your budget. Or wait until your current one just craps out. AirPods with a camera, I think, is a stretch. This may require a larger announcement coupled with maybe the Apple Glasses (also rumored to be in development).
Apple TV, HomePad (HomePod with a screen), and the HomePod Mini also make sense from a smart home perspective, and I would expect those to be lumped together as well. And Watch updates seem to happen. But the jump from one version to another often isn’t that big (depending on how Apple Marketing spins it). And Watches tend to last quite a while (I still have 1st Gen Apple Watch Ultra).
