It will be interesting to whether the base M2 SoC allows 32GB RAM. That would be a significant improvement, but I suspect it will not. I also don't think we'll see an M1/M2 Pro in the Mac Mini - Apple wants to push people to the entry-level Mac Studio I think.Yes, but what is there to configure on an M1 mini... from 8 to 16GB RAM is not enough... and that is what the OP (as well as myself) are complaining about. I personally do not need a Mac Studio M1 Max/Ultra for just higher RAM, is a complete overkill for my needs. Just need more RAM... Oh well.
As a thought experiment I specc'd a hypothetical M1/2 Mac Mini with 32GB RAM & 512GB SSD, the same as the entry level Mac Studio. It would cost $200 to upgrade the base $699 model to 512GB, and another $200 to get to 16GB RAM. Following the MBP pricing, it would cost another $400 to go to 32GB RAM, so a total of $1499. The upgrade from MBP14 7/14 core binned to M1 Max (24-core) is $500 which would get you the same price as the entry-level Studio. But this is from a binned M1 Pro, not an M1, so there doesn't seem to a lot of wiggle room in the pricing structure in which you could fit an M1 Pro Mini.
If the M2 base gets close to the M1 Pro in performance through faster CPU and GPU cores and an increase in the number of GPU cores, and has an option for 32GB, then we could probably live with the jump from M2 to Mac Studio with M1 Max....but then there will eventually be an M2 Max....so who knows!
