It is a good article, if a little too FCP X focused overall. I made my huge post on the problems that I have with extensive use of FCP X, and I wish Apple would deal with them before adding too much else, though collaborative editing might help with some of my complaints quite a bit, but there are still so many to go into.
I totally agree that Apple needs to knock it out of the park with a GPU, but not just for Cinema4D, but also for Premiere Pro (as well as DaVinci). And yea the CPU needs to really stomp ass with After Effects for sure.
An updated XDR display should happen quickly, and the new version should also be the basis for a new iMac Pro.
And yes the Afterburner card needs to be able to decode different codecs as well, not just ProRES, and that should also be either added to the iMac, or make a breakout box with BlackMagic and include the tech in that along with an HDMI out and in.
I really do wish I could afford a MacPro, though with the M1, it calls it into question. Be really weird if Apple ends up with the MacPro as the only Intel Mac, and a medium machine like the article calls for as M1.
