All the talk of the 5K iMac being dead, I bet it is more the parts shortage
I highly doubt the 5K 27” iMac is completely dead, sure it is dead for now, in favor of the much more expensive Mac Studio and Studio Display. The thing is that is a minimum $3500, much more than a base 5K Intel iMac. I think a 5K iMac isn’t dead, but with Studio Displays pushing towards a June ship time, Apple just had to chose one or the other. And especially if the Apple Silicon Mac Pro is pushed to 2023, the Mac Studio fills that high end gap much more successfully now, and once there is no supply shortage bet they do do the Apple Silicon 5K iMac that many have been waiting for.
