Agreed about the price; I just don't see how Apple using their own parts for CPU and GPU would shave off $3,000.
If they do re-do the iMac Pro line, I would need it to retain the 128 GB RAM I have on the current iMac Pro. That means two M1 Max parts. Still, that should be less expensive than the future Mac Pro with the same chipsets.
On a different note, what I'm really liking (not sure when Apple introduced this) was that you can now pay for AppleCare+ year-by-year (maybe this is only for certain models?). Thus, if folks need such coverage over say a 5 year period, you could then spread the cost of these Macs over that longer period and be covered the entire time.
