Mac Studio or the new Mac mini?

I am thinking of getting a Mac mini in the next dew weeks or the current Mac Studio. Maybe wait for the new Mac Studio in a few months that has more power, I think. I am a photographer and currently use an older MacBook Pro 16" from 2019 and although it works fine I would like to have something on my desk with a bigger monitor to replace my older Mac Pro from 2010. The Mac mini M4 looks like a bargain right now but since there are no more upgrades after purchase anymore this may turn out to be a problem in the future. I keep my computers a long time. I still use a Mac Pro from 2010 and although it works fine I can't upgrade to the newest OS due to its age.
