It would also cut into MBP sales, I’d think. They’re always going to want to maintain product differentiation.

For MBP give me one with 128GiB or even 192GiB RAM that I can run big local LLMs on.

I have an M1 Max MBP with 64GiB and I can run decently sized local models but 128GiB or more would run more serious ones.

While you could run larger models with 128GB, I feel like 64GB is just the amount needed to run models at a reasonable speed with a M Max (I have an M3 Max 64GB).

That's kinda why I'd like a 64GiB M4 Air. 64 is the magic number for local LLMs of any reasonable capability. Example: deepseek-coder can do unit tests, gemma3 can summarize PDFs and stuff pretty well, etc. You can't do much with LLMs with only 32GiB, just run baby ones.

M4 is going to be too weak on GPU, even an M4 pro is probably not going to get you far. If you go with an M4, 16 or 32 is fine. An M1/M2/M3/M4 Max is probably what you need minimum to run quantized 72b models, where 64GB is needed.
