I expect the larger iMac will probably launch at WWDC 2022, now I know it’s the age old Apple don’t release hardware at WWDC debate.. but historically their super high end products have got released or at least announced at WWDC in the past.
I expect a new chip probably called M1 Pro Max and launching in a larger sized iMac Pro and Mac Pro… I think the high end Mac Mini will probably launch via a site refresh between now and then also with the M1 Pro and M1 Max options.
This makes perfect sense as the two year transition was announced at WWDC 2020, so WWDC 2022 marks the completion of this transition and will give Tim Apple time to flex at WWDC.
Once all this is done I think Apple will then move onto M2 launching in the MBA, base Mac Mini and the iPad Pro in late 2022, I don’t think Apple will launch M2 whilst the M1 roll out is still going as releasing anything M2 between now and WWDC is likely going to confuse consumers as what chip is better etc…
I also have a feeling we may not see refreshes to the Mac or iPad Pro line up as quickly going forward, I expect 24 month refresh cycles for these products…
M1 Pro Max - WWDC 2022
iMac Pro, Mac Pro
M2 - Late 2022
iMac, MacBook Air, Mac Mini Entry, iPad Pro
M2 Pro / Max - Late 2023
MacBook Pro, Mac Mini High End
M2 Pro Max - WWDC 2024
iMac Pro, Mac Pro
M3 - Late 2024
iMac, MacBook Air, Mac Mini Entry, iPad Pro
M3 Pro / Max - Late 2025
MacBook Pro, Mac Mini High End
And so on…
