Of course, they could release the new 32" Pro Display XDR II with the option of adding a $999 stand that just happens to include the guts of a powerful iMac...
An interesting way of looking at it -- and probably a good reinterpretation of my suggestion from an earlier thread:
... And I know that others have dissed this idea when I've suggested it, but I still believe that a better fit for today's market would be a slick mount for a Mini on the back of a redesigned Studio Display lineup. Sure, a few third parties already have adequate rear mounts... but if it came from Apple and was made to look like the Mini actually belongs there, I think it would easily sell to many of us who still use and love our legacy era iMacs.
