I would be very surprised if they put out a M2 Pro mini. It would cut into the M1 Max Studio sales. It isn't Apples goal to maximize desktop volume by adding more incremental price points. Their goal is to maximize profits, and the entry level Mac Studio will sell well at $2000. If they wanted a Mx Pro Mini they would have already introduced an M1 Pro Mini last October when they introduced the M1 Pro MacBooks. I think they have created 3 tiers of desktops and the Mini will be the low-end only tier once again. The Mac Studio will be their broad mid-tier desktops at 2 basic price points, and the Mac Pro their elite upper-end desktop. My guess, of course.
