M2 is going to be based on A15, and M3 will be based on the A16. This is a logical outgrowth of what happened with A14–>M1–>M1Pro/Max. I think the cadence is not on a regular interval for the M-Series SoCs for a variety of reason, so there may be a skip at some point, but I don’t see Apple skipping a process node on a Apple Silicon generation ever, when they have shown they can get hella mileage out of the SoCs that they are releasing now. The M1 is not going anywhere for at least another 8 months, perhaps longer, which clearly shows that A14 was a bit of a watershed moment in A-Series development. I think the cadence is going to be closer to 18-24 months, which is fine for the Mac. The iPhone is a complete different animal.
