Overall, the current Mac mini with M2 Pro is still potent, the M3 Pro is essentially a sidegrade in comparison unless you have a specific need for such things as raytracing.I just got an M3 Air but I love it so much and would pick up an M3 Mini for at my desk even though I have a really high spec PC. It seems it won't be out any time soon though so who cares.
I really wish Apple would update the case and make it smaller tho, with the current architecture there is a lot of wasted space.
