After Apple added the note "While supplies last " to the product page of iMac Pro last Friday and removed all options for upgrades, rumors surfaced predicting its imminent demise.
Apple iMac Pro
And indeed, according to MacRumors, Apple has now announced it will stop production of the iMac Pro -- it will only be sold while supplies last. As a replacement for new customers, Apple proposes the latest version of the 27" iMac unveiled in August 2020, or for power users, the Mac Pro.

If the iMac Pro could still be equipped with up to 18 Xeon cores, an AMD Vega GPU, 128 GB ECC RAM, 4 Thunderbolt 3 ports and 4 TB SSD storage space, the 27" iMac comes after all (equipped to the max) with a 10th-generation Intel 10-core CPU, an AMD Radeon Pro 5700 XT with 16 GB VRAM as well as 128 GB RAM and 8 TB SSD storage.
In the future M1 iMacs?
But one may assume that Apple plans to introduce new iMac models as soon as possible, which run with a beefed up new version of Apple&s M1 chip - so far there are only the MacBook Air 13", MacBook Pro 13" and the Mac mini with M1 "Apple Silicon" on ARM basis. Although this is entirely optimized for mobile use due to its high performance with low energy consumption, desktop computers like the iMac or Mac Pro could also benefit from a more powerful version of the M1, which would require less cooling than the Intel CPUs used so far and come with more on-board memory (and perhaps the possibility to use external GPUs).

Rumor has it that a new iMac is indeed in development and will be released later this year that not only uses the M1 SoC, but also features a new design inspired by the XDR display.
