Yes, definitely. There is a HUGE space there for the M1 Pro Mac mini.
Speculation is that the Intel model is still sticking around for the time being because it is sells well enough to data centers (like Mac mini Colo).
I suppose there is a part of the market willing to spend over twice as much money for a Mac Studio because they need more power than an M1 SoC or they must have 32GB for their workflow and therefore the Mac mini just is not an option for them. But I expect that market is not that large, considering.
So offering a 32GB option for M2 and an M2 Pro option for the next Mac mini refresh likely is not going to steal a lot of customers from the Mac Studio. I expect the most-likely outcome is a fair number of people will upgrade an M2 Mac mini to 32GB because they just feel "gotta have it" and that's going to be a lot of $400 upgrades with huge margins so it might actually end up making Apple more money than depending on the folks who will pay $1000 more for Mac Studio after you factor in all the higher production costs of the parts in a Mac Studio.
But Apple lived quite happily for years with a big hole where the mythical xMac was placed. Only when the 27" iMac has seemingly been despatched has the headless box market suddenly become interesting - but the form factor of the Mac Studio doesn't look like it lends itself well to Co-Location on size and bulk grounds.
If we figure in a sales order from the Co-Location guys who don't want to have to reconfigure their data centres for life without the current Mini form factor how about this:
Mac mini goes M1 Pro only, retains existing form factor - gets 3 Thunderbolt 4 ports, more than the 2 Thunderbolt ports the M1 Mini has - keeps 2 USB-A ports, Ethernet, and the HDMI 2.0 port. Yes the bluetooth and wifi issues remain but Colo guys don't care.
16Gb/512Gb/M1 Pro spec starts at $1299 (which values the M1 Pro uplift at $200). And this uplift would simply raise the average selling price of the Mini for the people who can't quite stretch to the Mac Studio.
The usual options from the MacBook Pro 14" apply but for an extra $500 anyone who wants the display, keyboard, and battery gets the laptop.
I would argue that M1 Max BTO options may not be allowed for the Mini for heat reasons and to stop people from trying to spec up a Mac Studio on the cheap.
This frees up space for a Nano to be launched with the M2 CPU on its own schedule with 2 Thunderbolt 4 ports, 2 USB-A and the HDMI as seen before. As usual, prices from $699 with 8Gb RAM and 256Gb storage. Because it's a new product, Apple could then do something 'clever' like remove the Ethernet port on board to save space (maybe go with the iMac 24 PSU arrangement?).
It splinters the desktop line much more but gets away from Apple having to explain the differences between out of sync processors.
