I can't imagine the price dropping. Just considering the cost of the components, the CPU alone costs more than many decent desktop computers.
I suppose this hinges on the specific definition of 'decent', but the cost of the entry CPU in the $6K system only lists for $749

Technically that is less than the price of the entry level Mac Mini ( $799 ) . So it is less than the other Mac headless desktop option . There are plenty of Windows desktop that are under $749 , but whether they are decent for the kinds of workloads that the Mac Pro is primarily aimed at is debatable. A $200-300 desktop is 'decent' if all you are doing is reading email and web browsing.
$749 only represents represents about 12% of the Mac Pro. In contrast, the Core i3-8100B

It is more so the infrastructure that ships with the Mac Pro there is a bigger cost driver here. The Mini actually has a higher percentage allocated to the CPU. Same for other Macs. The recent MBA Retina. i5-8210Y
https://ark.intel.com/content/www/u...-8210y-processor-4m-cache-up-to-3-60-ghz.html $281 represents about 26% of the cost.
Those are two Core i processors that represent
HIGHER percentage costs of the overall system. The notion that all possible Xeon W choices ( versus Core i ) drive costs substantially higher than other Mac systems is more myth propagated on these forums than grounded in fact. It is related ( having 6 DIMMS slots costs more and that is enabled by the CPU, but the CPU's cost isn't the direct factor. )
This $6K price is a bit funky. There is a pretty good chance that Apple has buried several $100 in this system price as a "low volume, but more software " tax. The parts don't particularly match up even with 30% mark ups.
case $1K
32G RAM $1K
SSD $200
LogicBoard $1K
Power Supply $900
CPU $1K ( liss for $749 )
$5.1K ... still missing about $800.
If you want a cheeper computer you are going to need something much lower spec and with much less expandability. Cricky even the 1400w PSU alone is in the £400 mark for a gaming grade one, a workstation supply is likely to be more expensive as it will be expected to last a bit longer and run 24/7/365 for years at a time.
Whether the power supply lasted longer would probably matter more on how clean the power provided was and the loads applied. Doubtful getting something that can be abused to a much higher degree. It is custom sized and the thermals cooling paths needs to all match up with the airflow provided in the Mac Pro ( i.e., they can't be used in any other system so highly custom ).
In short, due to all of the highly custom construction that is driving the costs higher, so the base price probably isn't going to move. If Apple is shorting on SSD capacity side that they will 'crack' on the base price. There is likely "other stuff' that they want paid for that most folks aren't allocating for.
