Any chance we got this all wrong and the new MacPro will be Intel based? After all, Tim did say they had an Intel Mac coming and the new Xeons are set for the end of Feb.
What Apple said was
"...
Apple will continue to support and release new versions of macOS for Intel-based Macs for years to come, and has exciting new Intel-based Macs in development. ..."
Apple today announced it will transition the Mac to its custom silicon to deliver industry-leading performance and powerful new technologies.

That was June of 2020. In August of 2020, Apple introduced the Intel iMac 27" ... finally getting the iMac off the non T2 (non transition, 'T' ) status. Did Apple ship multiple new configurations of Intel iMacs in that 2020 update? Yes.
Apple didn't explicitly say "new Intel-based Mac products in development".
Technically Apple satisfied the multiple Mac units being shipped before the M1 units made it out the door. 10,000 iMacs is an entirely valid usage of the plural word 'Macs'. ( The developer kit shipped
before the new iMacs; so technically shipping 'Apple-Silicon' actually had already started. Some folks hand wave at the iMacs release as before the Apple Silicon era. That is a lot of mental gymnastics. It was the Developer
Transition Kit ... if you were not running macOS on Arm what was it running? And the Intel transition kit wasn't really running Intel huh? Not. )
. The twist of 'new Intel-based Macs' is that it is talking about multiple Model model numbers as apposed to multiple actual Mac units. It is probably the case that Apple was talking about timely Intel follow ons.
Okay so I have a short and sweet update on Intel's upcoming Sapphire Rapids-SP, Sapphire Rapids-112L and Sapphire Rapids-64L platforms. Officially dubbed the 4th Generation Intel Xeon Scalable Xeon W-3400 and Xeon W-2400 CPUs and powered by the company's W790 platform, Intel is gearing up for...

It is very probably not these. The last, May 2020 , Intel MBP shipped with IceLake ( mainstream Gen 10 ) processors in them. If Intel's 2017-2018 roadmaps had kept to schedule the Xeon W-6300 (IceLake) CPUs would have coming in late 2020. If those CPU packages had arrived on time and on thermal budget then they were a much, much better much with the 6000 series MPX updates that Apple also had lined up ( provision PCI-e v4 and GPUs take PCI-e v4. no mismatch. )
The W-3300 didn't 'launch' until almost mid 2021. They were much higher on thermals. The performance was middling if didn't use the new AVX-512 ( which Apple was
completely ignoring in Rosetta) and AI/ML augments. Single threaded it wasn't much of a bump at all. The 38 core model bumped into macOS 64 thread limitation.
About the main upside it would have had for Mac Pro would have been slightly more competitive pricing versus AMD's line up. (not huge but Intel knew they were in trouble).
The W-3300 series got skipped by Dell/HP/Lenovo. (largely because even though it was paper launched Intel never put tons of die allocation to the line up. Too busy trying to save the rest of the Xeon SP line up). So Apple dropping that project wouldn't have been a big leap. ( several other vendors dropped it too. )
It would also have been a leap from one dead-end socket to another dead-end socket. Not that Apple would likely go past.
When the W-3300 collapsed on itself as a timely solution, Apple's 'Plan B' was far more likely just release the 6000 MPX modules by themselves on the 2019 platform they already had. That is the much more inexpensive route.
There is a small performance knock by not having matched PCI-e v4 backhaul, but it was far better than nothing.
If the W-3300 had been better than Intel said with higher all around performance with zero Thermal overhead increase and arrived ahead of schedule. If Intel was inclined to attached unusally long term support to these that might have helped also. Apple probably would have used it as a much better 'gap filler' early 2021 product.
The 2018-2019 road maps for W-3400 were into 2022. The Xeon SP Gen 4 was suppose to be late 2021 on those roadmaps and the W series typically came much ( 1-2 Quarters) later. So Apple had a plan in 2018-2019 to launch a new Intel Mac Pro in 2H 2022 ... right when they were projecting to
finish the Intel transition? Probably not. Remember Intel already had screwed up lots of roadmap deadlines by 2018-2019... if Apple added in the "probably not telling the truth" fudge factor for those 'mid-2022' arrival times for W-3400 they'd end up with 2023. Which is the year after they were suppose to be done. While Apple said they were going to support macOS on Intel for years , they were not in anyway suggesting that they were trying to maximize those number of years. After 2022, it was probably going to be on the clock toward retirement.
I suspect some folks are thinking Apple is in some kind of desperation mode if the quad-die/"Extreme" package fell through and will quickly whip together a W-3400 update to stall for more time. That is unlikey. It took 2017-2019 to get to the current Mac Pro. Apple whipping something together hyper fast? Probably not. If it wasn't on the road map 12-18 months ago it is probably not happening.
The other huge problem is that the Intel Mini just got dropped. The iMac 27" has been dropped for almost a year. There is not even any other Intel Mac product 'limping along' in 'low key' mode in the background. All the other Intel "No Mac Pro" Macs are actively on the Vintage/Obsolete countdown clock. That huge inertia is going to take macOS on Intel down. No way the Mac Pro is going to 'swim upstream' in that roaring current heading the other direction at this point.
Apple is already committed to several years of macOS on Intel support for the Mac Pro 2019. At best, if they needed a cheaper "plan b" to extend gap time they would do the same thing they did in 2021 ... toss out one or two GPU cards. Even that is a stretch given the current environment of 'dead end' 3rd party GPU support. However, the overall system relation to operating system lifecycle suppor term probably wouldn't change. (new GPU isn't going to extend the overall macOS on Intel countdown clock much at all.)
