That.
If you look at the iMac Pro pricing, which does not give you that much of headroom at all, I'm sure the new Mac Pro pricing will be outrageous.
The next thing to consider is the missing display, which will not make it cheaper for the consumer, because Apple will certainly not price the Mac Pro entry level without display lower than the iMac Pro.
They need to sell the iMac still. It has a very high margin.
My guess is that the "base" configuration that no-one really wants will be $7000, because if you "need" a Pro device, this is what you have to pay.
So, Yes I would be interested. But No, I will certainly not buy one considering Apples idea of pricing.
