Knowing Apple, they don't want a bad name for the actual image quality which is fundamental to this product, so I don't feel they will really want to mess with the display very much. Perhaps a very slight downgrade, but not enough to be very noticable.
Lowering the two 4K screens' res would mean for users to see pixelated surroundings. So, knowing
Apple, that won't happen.
The first and most obvious thing I can see being removed is the Spooky Eye display screen on the front. Many reviews have even suggested this may be scrapped anyway, so I feel that's an easy thing to go and save costs.
I could understand such a move to reduce costs, but if you think of it, it's also the ONLY headset with this feature, and Apple always wants people to distinguish their products, not just for the quality, but for the features. Also, I think that's a simple LCD screen, pretty cheap.
So, all considered, I doubt they would remove it.
Then we can scrap the expensive curved front glass as that won't be needed.
No we can't. The curved front glass is an engineering feat, since it allows all cameras to see the world as it is, without distortion. It's not just for beauty. It needs to be rounded.
Eye tracking I feel will stay along with the hand tracking. But I feel they may be able to use more machine learning to simply remove a few camera's and still do the same job.
I see your point. But think about it: won't more machine learning require a more powerful processor?
That would require for a better - hence more expensive - Mx and Rx SoCs.
Perhaps a plastic housing? But then Apple are not really into Plastic, so I'm not sure about that.
I think the metal is necessary for better heat dissipation. Unfortunately, plastic is terrible at that.
The headband, perhaps a little cheaper, but I can't really see that making much of a price difference.
Speakers could be removed, or made less impressive and they could push more towards a cheaper version and suggest airpods if you want higher quality.
This would make sense. But then, wouldn't we need a pair of earpiece to connect to the device? These would probably cost more than the Apple Vision Pro integrated ones.
They are actually making around 100% profit on the current headset and not much will actually be removed.
It will just be cut in price, stay pretty much the same, and a higher end model will appear to become the next pro model.
This.
I mean, they won't make 100% profit, nor 50%, since production costs for high-end tech won't go down so much in such a short time. But yeah, this is the way they'll go, imo

Which is kinda good, because it means they'll keep the bar high, only making better headsets!
