The Mac Studio might replace the high-end 2018 Intel Mac mini, which has a base price of $1.1k; so an argument could be made for Apple also offering models with the M1 Pro SoC (single SoC only)...
That $1.1K start point is flawed because neither the M1 Pro , Max , or "Double Max" can limbo down to 8GB of RAM. The 16GB minimal on that same system is $1299. And that would only if a M1 Pro was going in there which is highly doubtful. The "floor" for M1 Max RAM is 32GB for which the current Intel Mini starts at $1,699. That would be the minimally creditable starting point.
However, if starting with a M1 Max , instead of a Pro , then $400-700 needs to be added on (gap between Pro and Max in BTO). So probably this would start around $2,099.
That is probably closer to the what it will be. First, that cleans out any substantive fratricide for the iMac 24". It probably also clears the entry iMac Pro (with a M1 Pro) also once add a decent 3rd party screen to this "Studio" entry configuration.
Between the MBP 14" and 16" and upcoming iMac 27" and likely M1 Pro Mini , Apple probably doesn't have a problem generating unit volume consumption to drive economies of scale for the M1 Pro die. The more pressing problem is going to be the M1 Max and any double configuration of the Max sized dies. That is where they need the unit volume build. Stuffing Pro sized dies into the Studio doesn't make much sense.
Either Apple keeps the current Mini case and stuffs a M1 Pro and Max in it for a "mini pro" or they chop down the case to the M1 Pro size thermals and do a M1 / M1 Pro class variant. Either way the volume contribution for a "Pro" die volume is met.
Apple set the stage for a $2-3K in-between headless Mac when they jack the entry point of the Mac Pro up to $6K.
That is probably the hole they are probably going to try to plug with this headless option.
If Apple does a $1,200-2000 27" screen ( more affordable than an XDR). then iMac 27" will look like a bargain if the "studio + Apple 27" is > $3K.
The "double Max" will likely be up in the over $3K range. Around $700 for the additional die and bleeding edge packaging and the RAM floor will be 64GB (so at least another $400) for that also.
If there is no internal storage expansion, then 10GbE should be the minimal networking on this thing. That will add to the base entry configuration cost also. [ if forcing folks off onto NAS/SAN storage then it is time to get into 21st century NAS/SAN storage speeds standard. ] . Again, Apple has the Mini for the folks with limited spend budgets. About zero sense if making "another" mini in the line up.
