Apple discontinues iMac Pro, available 'while supplies last'
Apple appears to have discontinued the iMac Pro, with the Mac model now only available in a single configuration but only "While supplies last."

An update to the online Apple Store's iMac Pro listing late on Friday has severely limited the potential purchasing options for the model for customers. The change seems to indicate Apple is in the process of discontinuing the model completely, and is in the process of selling off its last units.
The store page includes the text "While supplies last" at the top of the page. While customers were previously able to configure the iMac Pro with different specifications, there's now only one option available to purchase.
The sole option offers a 3.0GHz 10-core Intel Xeon W processor with 32GB of 2,666MHz ECC memory, 1TB of SSD storage, a Radeon Pro Vega 56 8GB, and 10Gb Ethernet. It is priced at $4,999, with no options to upgrade or customize the order from Apple itself.

Previously, there were configuration options for 14-core and 18-core processors, Vega 64 graphics, up to 4TB of storage, and up to 256GB of memory.
The change does not apply to third-party resellers, who will have some stock of other configurations on hand.
While Apple hasn't declared the model to be discontinued, the minimal choice of configuration and the "while supplies last" warning strongly point to Apple discontinuing the model. It is unknown whether a new version of the iMac Pro line will be available in the future or if it will be absorbed into the main iMac range in a future product line update.
Since its launch in 2017, the iMac Pro has received some specification updates, but no major upgrades to the design. There was some speculation of an updated model in December, though the supply chain rumor didn't offer any real detail about what was on the way.
Apple is also on an aggressive two-year timeline to migrate its Mac products from Intel processors to Apple Silicon, but it seems unlikely that the iMac Pro would be a part of that. Apple is thought to be preparing a redesigned iMac with Apple Silicon for release in 2021.

New iMac Pro is the rumored iMac with a Pro Display XDR design
Standard iMac inherits the dark graphite colorway from the old iMac Pro and bumps up to 6K and 32 inch
New entry level iMac becomes 5K 27 inch and has the rumored multi-color approach
I believe the idea of an “iMac Pro” has merit, but it’s hard to imagine how it will fit into an Apple Silicon lineup. The only way would be if it were used for an iMac with a professional XDR display built in (whatever the size). I don’t think we’ll see XDR technology trickling down to the regular iMac line any time soon. It would be nice to be wrong!
The entire 27” iMac line is going to stop. That giant aluminum housing will stop being produced and every variant of it, I’m sure. The iMac Pro is the first due to it likely being the lowest volume, but the 27” tapered iMac is done for certain, shortly.
But for many of us mere mortals, a simple 5K iMac display is very nice. One of those in M1 cloth would be huge. Though it's out of the realm of my consideration, I'm anxious to see what the new iMac Pro will entail and whether or not it will be cheaper than this last line of iMPs.
Somebody earlier said that it’s highly unusual for Apple to literally say “buy this machine while you still can”. I think it’s a tacit acknowledgment to the corporate buyers who normally get this machine that if it’s still a standard in your shop and you need one, get it now before we close it out.
As for me, I’ve been seriously tempted by the current Mini to retire two 2008 Mac Pros still working in my home but I think I’ll hold out for the M1X for a few reasons (more cores, hopefully 10 gb Ethernet).
If Apple does eventually issue a formal "discontinued" announcement, it would not be the first time. Although products sometimes seem to vanish into thin air, Apple did officially discontinue the Intel MacBook Airs, Thunderbolt Display, and 15.4" MacBook Pro. And many times over the past 20 years, a product page has been updated with a "Discontinued" notice as shown in this article:

In any case, it's not clear what an official announcement would add. It's obvious from the fact that something can't be purchases that it is discontinued. People seem to be inferring that the announcement means it will never be offered again, but that makes no sense whatsoever. Apple could intend to discontinue it permanently today, then change it's mind in 12 months.
They could release 24” or 32” Pro Display HDRs with the Mac or Mac Pro designated by the processor card you’re plugging into it. Same for redesigned desktop & notebook chassis.
This is going to be interesting.
But nothing is forever. It’s going to be interesting to see what future M series Macs can do in that space.
