Hence the "Pro" designation - it was 100% obvious that one was coming. The real question is what will Apple compromise to get a lower cost Vision to the masses?
They won't take anything away. Or at least, they won't compromise on the key things that make it good.
Right now they call it "pro" and keep the price high for early adopters and tech enthusiasts who will pay it.
Then they release the regular version.... alongside "Pro 2".
Pro 2 gets some fancy new features, while the regular version (and cheaper version) hits much of the same performance as the Pro 1 but for a more reasonable price.
So everyone is happy: early adopters got to have Pro 1 while everyone else had nothing, people who waited get a cheaper model that is just as good as this version, and enthusiasts who have $ to spend get to upgrade to a Pro 2 that is even better.
That makes sense given they just started doing that with the iPhone.
The regular 14 got the chip from the 13 pro while the 14 pro got a new one. The regular 15 will get the 14 pro chip and most of the features like the dynamic island, while the pro will get the new periscope camera and some new features.
I think one of the big differences will be with the speakers. If they make the standard model require AirPods, they can eliminate speakers entirely and save significantly on cost.
Another possibility is moving from metal to plastic for the frame design. This saves on cost and weight. They could also take out the 3D camera.
I strongly believe they won't compromise on the display resolution or the EyeSight feature, though it's possible they'll be able to fake the lenticular effect using software and opt for a simpler outward-facing display.
