It'll be interesting to see how long Apple sticks with the 10.everything scheme.
Condsidering they went with it for so long I consider any change at this point to be very vast and to come with structural changes to the underlying platform...
Now you could be arguing for days how that may pan out, I think ultimately it's going to be dictated by practicability.
If the move for Mac to ARM were to happen it's going to see a uniform access to apps for both macOS in the form of macOS allowing access to "iOS apps" as a feature, later on both might get merged with each becoming optional "universal binary" options for the developer.
Now, personally I think the x86 platform offers way too much edge over ARM which is part of the RISC family of processors (where the hint is in the name - Reduced instruction set computer).
However, with the recent moves by Apple I'd be hardly surprised to seem them go this way.
Maybe as a co-processor?
Either way... That might be the time when they make a new name rise above the trusted X "brand".
Another guess from mine is that they might push any drawbacks to later releases...
Examples:
x86 Support will likely remain existent natively to the first couple of generations until "app support" advocates ARM as single-support architecture.
Apple might be wisely advised to heavily Incentivize devs to at least "also support" ARM during the first few releases. (It'll be extremely exciting to see Parallel's and VMWare's moves)
Once that's done they can claim the new gen of Macs has 9x% support of "Mac App Store apps" support (another case of tough **** for legacy lovers... there will be "legacy x86" support in the form of a "Rosetta"-style implementation)
I'll be very blunt with you guys, I don't want any of this to happen. I've long considered my future Mac putchases to be mostly home office-level purchases. Heavy [x86] tasks will likely mostly be relegated to Windows on a self-built machine because beefy raw computing and gaming doesn't necessarily require Mac these days for my tasks.... Hell even my Adobe alternative Affinity Photo and Designer launched for on Windows...
It's not the same, but as a semi-professional I need to keep my spendings in check. Maybe Mac Pro will remain x86-ARM hybrid, but I really fear that we might see a shift to ARM in Mac.
Maybe i3 to keep basic x86 compatibility for Bootcamp and easy Parallels and VMWare suppport as well as legacy and pro apps support on some level...
All just guesswork. Felt like doing a good old type down though. Looking for open discussion!

Notice / tl;dr: I'm drunk, should be light minded, still came to MR and felt inspired to share my thought about the platform / ecosystem that re-ignited a new joy in computing in me over 10 years ago. I really love Mac, iOS (as limited as it may be... Maybe one day we get the optimal mix of Android's openness and iOS's privacy) and anything else Apple [that they still offer... ugh]
