My thought is that it would be best for Apple to release the M2 Base at the same time as the Pro/Max versions. Push the launch of the new MacBook Air until end of May or early June (just before WWDC) and also include updates to the MacBook Pro 14" and 16" with M2 chips.
Launching the M2 which could potentially outperform M1 Max in raw CPU (estimated 25% improvement of performance per core)... meaning that the baseline chip should beat both Single Core and Multicore tests... just wouldn't sit right for the Pro community unless there was an M2 Pro/Max update for them. At least having 7 months with M1 Max being at the top of the mountain would be better.
Personally I feel like they launched the M1 Pro/Max too late in the year. It has already been a full year since the first M1 was announced. They did say it was going to be a 2 year transition, but I have a feeling that all of the major machines will be converted by WWDC next year with a few Intel options still hanging around.
I would not be surprised to see an Intel iMac (current body) update coming at the first of the year... it all depends on when Apple is going to get their hands on the new 12th Gen Alder Lake (OEMs getting them Dec/Jan, right)? No major announcement, just a minor speed bump for those users that require Intel chips for their workflow (Apple did the same thing with additional G5 updates during the transition to Intel a few years ago). Possibly an updated Mac Mini as well. I personally have web development stuff that I would like to have a 12th-gen Intel chip to run VMs on a headless mac mini and I am sure that there are a number of other people in the same boat.
The big question is when is the 27"/30" iMac going to be released with an Mx chip? Are they going to wait until the M2 announcement and release the iMac at the same time as the MacBook Air?
Yeah, none of those things are going to happen.
Especially with the current chip shortage, and just how Apple‘s update cycles have been working lately, don’t expect a new MacBook Pro until at the absolute earliest October 2022. More likely somewhere between March and June 2023.
There is not a chance that they introduce the M2pro and M2max only seven months after the M1pro/max.
This isn’t like the old Intel MacBook pros where the schedule was an absolute mess, or like the 2012 iPad situation where they rushed the fourth GEN out to switch everything over to lightning.
M1 series is here to stay for quite a while.
If rumors go to plan, which my guess is that they probably will, we will see the M1pro/max come to both a Mac mini and a 27 inch iMac in either Q1 (most likely March) or Q2 (WWDC in June) 2022.
The iMac will most certainly not be getting 12th gen Intel processors, it already got its last Intel update in August 2020. Everything from here on out, with the tiny possible exception of the Macpro, will be Apple Silicon only. Tim said the entire transition will be completed within two years, and the first Apple Silicon computers came out in November 2020. So that means you can expect by November 2022 that Intel will no longer be in the lineup.
And then the M2 MacBook Air will most likely come out in Q3 or Q4 2022, with the MacPro being The final product to switch over, probably coming right at the tail end of 2022.
