After watching today's WWDC product announcements regarding the Mac Studio and Mac Pro updates, I really don't see myself ever buying a Mac Pro in the future. While I can understand how very large studios may value the additional expandability, a massive case with ability for expensive upgrades just isn't something I would need or pay extra money for.
It looks like Apple has targeted the Mac Studio for the largest number of professionals, while reserving the Mac Pro for a niche high-end market - and in these regards, the Mac Pro is a continuation of the 2019 Mac Pro, whereas the Mac Studio is a continuation of the trashcan 2013 Mac Pro.
