"....And it's a gap that would be filled by a tower or mini-tower Mac that sits between the iMac and the iMac Pro in price and performance."

The Mac Pro is the missing link, it just isn't priced for it.
If I travel and want to bring a Mac where I can continue working with RAM and storage-hungry libraries, the MP isn't a good solution, due to it's size. The MBP can only house 32 gb. The most powerful Mini could be a good solution, but also has it's limitations. So IMO, we need something which...
- doesn't have a built in display
- allows us to install the RAM and SSDs we want (at least up to 128 gb, but 1.5 terabyte isn't needed), and, say, up to 4 SSDs
- to reach a large enough market, it should cost a lot less than the entry level MP with 32 gb RAM and and 256 gb SSD
- it should come in different degrees of CPU power, including a solution with good multi and single core performance
- it doesn't have to be as tiny as the Mini, but should be a lot more portable the the old and new cheese-graters
IMO, the new Mac Pro isn't the missing link, it was a missing
product – and it's great that they have produced it. The 'missing link'/ gap, the way I see it, would be more like a mid priced iMac but without the display, or a 'Mac Mini Pro', or a MBP with at least 8 cores and 64 gb RAM but no display/keyboard.
If you ask 10 people about what that missing link/gap would be, you'd probably get 10 different answers. But in general, it's somewhere between the size and price (and weight!) of a 1 kg Mini and an 18 kg Mac Pro.
There was some speculation that the next modular MP would have been modular also in terms of different modules one could buy and place on top of each other. Such a solution would have allowed a more flexible level of modularity, in that it could be purchased without any PCI slots, but allow us to buy a 'PCI slot module'.
Another module could allow more and/or different connectors – and so on. If each/most of these modules looked like a Mac Mini (in different heights), one could also have a module which could house several SSDs. I don't think the upcoming MP is the last modular solution Apple will make for the reasons above – and because an even more modular concept would be built from the ground to be able to satisfy users with very different needs (and income).
