I'll see myself out.

M3 seems to be the next big jump so it could be then. A switch to 3nm plus armv9 seems to be a good combo for a performance boost
It could also be a good time for them to add the following:
I highly doubt most of those features are coming any time soon, but a guy can dream
It could also be a good time for them to add the following:
- 32gb ram on base chip
- Additional external monitor on base chip
- Ray tracing cores
- Sim Card support
- Wifi 6e
- HDMI 2.1
- Bluetooth 5.2 or 5.3

The version is somehow irrelevant to Apple now because Apple can implement pre-released arm spec's feature in their SoC if they want to like how they implemented FEAT_AFP with vendor specific registers in the Firestorm Cores. FEAT_AFP is in ARMv8.7-A and ARM talked about this extension on September 21, 2020, A14 released even before that, on September 15, 2020. If there is anything useful to Apple they probably have implemented that already instead of waiting for a new spec.

eSIM you mean? That probably depends on when they finally get that modem rolling.
Hoping to also see > 2TB max on base chips.
Probably that. The ability to connect to the internet via cellular without having to tether off my phone
That means extra cost and the 5G modem price nowadays is quite... substantial due to Qualcomm monopoly, just look at how much will it cost you to add cellular to an iPad.
Rumor has it that M2 Pro and M2 Max will be manufactured on TSMC's 3nm node and will be ARMv9. (According to ShrimpApplePro)
Definitely, but one doesn’t have to implement fill armv9 for SVE2
That isn't exactly common knowledge like how to ride a bike. They asked a question so they can better understand a topic.
No. M1 is on N5, M2 on N5P, so for M3 to still be on N5 would be like anti-progress. I was hearing noises to the effect that the Pro/Max/Ultra M2 versions might show up in N3 – the M3 SoC might well be on TSMC's GAA-like N2 process.
LLVM 15 was released today and has support for Armv9-A, Armv9.1-A and Armv9.2-A architectures.
Is this a requirement for Apple to adopt Armv9 in Mx SoCs?
What is the difference between Apple's LLVM fork and vanilla LLVM?

No. LLVM does not dictate hardware design. That's the whole point of LLVM.
Edit: I just reread your post and I guess you were pointing out that ARMv9-A is an update to ARMv8-A, also known as Aarch64 which Apple’s SoCs are based on. So does LLVM’s support of ARMv9-A indicate that Apple may also be adopting it? Could be, given Apple’s historical ties with LLVM— maybe check the commits for clues. It’s worth mentioning that Apple is certainly not the only implementer of ARMv8-A, though, so LLVM is probably just ensuring industry support.

Little. But then again, presence of ARMv9 instructions in LLVM doesn’t mean that those instructions will be in tomorrows (literally 😀) A16 SoC either.
We just don’t know how Apple engineering regard these things. And I’m not sure we can draw extensive conclusions about future hardware from tomorrows phone SoC either.

Just a quick note on this: LLVM supported code generation for these ARM profiles for a while. If so understand the latch correctly it just adds new compiler options that enable certain group of features, that’s it.
