studio display has the old imac screen quality and real estate...probably the new one will be 32" promotion mini-Led display
If Apple are going to offer 32" Promotion, why build it into an iMac and sell to a niche when they could make a standalone display and sell it as an accessory for MacBook/MacBook pro (
far more potential customers) , Mac Minis, Mac Studios , Hypothetical future Mac Pros... the first group probably outnumbering desktop customers by a good margin, the last two often in the market for dual display systems...
Remember, with Intel, the desktop Macs offered more powerful processors, GPUs and more RAM than laptops. Plenty of people bought some type of MacBook for portability and an iMac for power. With Apple Silicon (short of the top end Studio Ultra) that advantage is mostly gone. If you have
any need for mobility it probably makes more sense to buy a M1 Max MBP and a large screen/docking station like the studio display.
The problem is, Apple doesn't have mind control. Not everyone wants to fork out $3,600 for the Studio combo.
The iMac Pro
started at $5000. A credible replacement - 32 GPU/1TB Studio + Studio Display comes in at $4000.
The Studio Ultra is more comparable with the 18-core/64GB iMac Pro that cost about $8000.
A top-end i9 iMac came in at around $3000 - $3200 - and remember that was for 8GB. 32GB from Apple would have cost you another $600 - the Studio+display option is only more expensive because you've lost the option to save $500 by getting third party RAM (I'm not giving Apple any kudos for that but - face it - the DIY RAM option would have gone away anyhow).
The gap comes if you wanted a lower-end 5k iMac. Still, the "small" iMac now has a significantly bigger screen and is more powerful than before...
At this point I'm starting to doubt whether there will be a new Mac Pro!
I expect there will be
something called a Mac Pro, but it is far from obvious how Apple is going to use Apple Silicon to match the main selling points of the Intel Mac Pro: massive RAM capacity, massive PCIe bandwidth & support for high-end PCIe GPUs - when Apple Silicon's big selling points are TB4 connectivity, unified RAM and tightly integrated GPU. Time to "think different". Supporting the 2019 Intel MP for another few years while they develop the Studio as the "new Mac Pro paradigm" would make more sense.
If you ignore the 2019 MP, the Mac Studio is the spiritual successor to the Trashcan Mac Pro (and works out a lot better).
My guesses (nothing more):
* 1U Rackmount version of Studio Ultra (matching rackable TB4 PCIe enclosure and storage from 3rd parties)
or
* Mx Max/Ultra/Extreme 'compute modules' in Mac Pro MPX format, for existing Intel 2019 Mac Pro or new "slots only" enclosure
