I just heard Dan from Macrumors says on his Video posted on YouTube some minutes back that he thinks his best guess is, some mechanism of FaceTime Components still not permitting them to put the camera in Landscape Mode on the Pro.
Well, if they can do it on the new base model Ipad, I'd assume it's not the camera itself. Maybe it's the location of the charging coils/magnets for the pencil. Which means they'll need to move them or tweak it in some way, which means more opportunity for them to make.....wait for it.....a new Apple Pencil! Same capabilities, but only works on the next model.
I see one of two things happening here.
1. I saw rumors start popping up today that Apple will put a foldable screen on the ipads first before they bring it to the phones, basically as a beta design, before they bring it to their main product lines. Target date mentioned was sometime in 2024, So maybe put all engineering efforts into this and make that the next main body redesign. In the mean time, they just needed to come out with something "new" enough now so that the product didn't sit on a 3-4 year refresh cycle.
2. Something wasn't ready for in time for their normal refresh cycle, probably due to supply chain (3 nM, larger screens, etc.), so this is just a temporary place holder because it's easy to implement, is technically new, and it will enough of a refresh to provide a blip in sales until the real thing gets sorted out over the next 6 months or so.
I tend to lean more #2. My reasoning being, we know the Macs are getting pushed, probably for similar reasons on the newer processors. Because the Ipads were always targeted to use the base M2, which has been out for a few months already, and their normal refresh cycle time was up, I think they just put in what they could at this point and punted until they get the other stuff sorted.
