No doubt they will come. The M1 powered all of the low end stuff, including the Mini and the 24inch iMac. These new chips will power power laptops and desktops, Mac Mini high end and mid to high end iMac's.DAZZZZZZZZZZLING!
I wish MAX would have also rolled out in ANY desktop box: rumored Mac Mini Pro, Mac Pro Jr, iMac 27"-32" or just Mac Mini as a BTO option. Yes, that's probably coming 6 months from now in something(s), but I wish these had a non-laptop home right now too.
Not sure if the iMac Pro comes back. If so probably a future higher end chip, that is also in the Mac Pro?
