The MacBook Pro stayed on Intel for months after the M1 Air and Mini were launched.
They stayed on M1 Pro/Max for months after the M2 Air rolled out.
I can't remember a single time in recent history - Intel or Apple Silicon - when Apple updated the
entire Mac range - or even the
entire MacBook range - in one swoop.
Everybody is on the back foot with this latest event - but since
"Scary fast" is the exact same tagline used for the M1 Pro/Max MacBook Pro launch, Apple have near-as told us that it's going to be new MacBook Pros, even though that would break the usual MBA-first release schedule...
The mystery is what, if any, other machines get M3'd at the same time - it is even possible that they've decided to lead with the M3 Pro/Max (or maybe change the naming scheme) and the regular M2 will hang around as the "low end" option for a while. Maybe Apple will break with tradition and upgrade the whole range (or the whole laptop range) for a change.
