A shame really. Might be releasing an intel Xeon version simultaneously just to tide over ?
Hight Doubtful for several reasons.
First, Once get past the two year mark of announcing going to do a two year transition away from Intel 86_64 to Apple Silicon the chance of a 'new' Intel system shipping is pretty dismally small. That would be akin to Apple saying they were going to bring back 32-bit macOS apps. Apple has committed and burned that bridge behind them so extremely hard to go back.
There was a 'window' for an Intel update for the Mac Pro in 2020-2021, but once past June WWDC 2022 that is probably done.
Second, Which Intel offering? The Xeon W3200 class that Dell, HP , and most of the major vendors have skipped? Probably not. Runs really hot which would bump at the limits Apple designed for. The W3300 which pushes the top core count well past the max tread levels macOS supports and additionally seems to be possibly sliding into 2023 ? Highly probably not.
The other major problems is that without all the 'volume buying' discounts from the rest of the Mac line, Apple wouldn't have any more clout at Intel than a common white box system vendor. There is an article about how Apple even dropped buying Intel Thunderbolt redrivers for the latest M2 MBA. [ Probably will stick with Intel a while longer for actual discrete TB controllers. ]
That chatter about a AS Mac Pro also had a M2 Pro Mini that was going to wipe out the remaining other Intel model. Once, the whole rest of the line up switched the Mac Pro is likely going also. Apple can keep selling the 2019 model (7,1) for a couple of more years.
As more and more of the Intel Macs fall onto the Vintage/Obsolete list the developer allocations for macOS on Intel is likely to dwindle. There is no rational sense in building a new Intel Mac is if there is no macOS to put on it in several years. ( Essentially same core problem with flipping to AMD workstation option. the x86_64 macOS is going away. )
Third, even if Apple rolled out a W3200 workstation in late 2022 it would be competitively crushed by the AMD Threadripper 5000 and upcoming AMD 7000 / Nvidia 4000 options. It would be close to the Mac Pro 2012 all over again. Capture of a few folks that just want to stay deeply tucked into the macOS ecosystem but heavily compute challenged folks will likely be moving. If they do drivers for the AMD 7000 with an update then lots of 7,1 won't upgrade their systems. If don't support the newer cards than the systems lags behind.
I have no gripes with the above scenario (40 core CPU 128 core GPU )…the GPU will be good enough to drive displays with all the bells and whistles…maybe touch 3080ti performance with gobs of ram
That is the other problem with another Mac Pro is that if sold alongside a new AS Mac Pro the total market is going to substantively shrink. The hyper modular folks like to claim that they are the whole "Mac Pro" market base. That isn't factual. They are a subset and will be a smaller subset after Apple peels off the folks who need cost effect performance more than hyper modularity. So will sell even fewer Intel systems than the 7,1 did. Again a shrinking pool of potential users.
I though would love to see a 256/512 core! dGPU compute card…as an optional ‘module’. Might be expensive thing
What matters is not whether will look and ogle at the hyper expensive thing, but whether enough folks will buy the hyper expensive thing. The gold case Apple watch was a bust. M3 or M4 generation will probably bring that as a non dGPU. Some folks will grumble and squat on their 7,1 for years and the future iterations will get backs and some will take the exit ramp (because it is good enough for long enough for reasonable ROI. )
Apple will continue to disappoint for some :/
And somebody will complain on macrumors about what Apple does no matter what they ship. Apple isn't in the do everything for everybody business. Never where ( at least when a profitable company )
