Keynote is this coming Monday! Its still not looking super solid, even on the rumor mill side, but I still hold out hope for a significant upgrade to Apples Pro offerings: https://www.macrumors.com/guide/wwdc-2019-what-to-expect/ With all they're throwing into eGPU support, I have to guess that they plan a "Modular" Mac Pro to be upgradable with external modules, rather than giving users access to the gut directly like they last did with the cheesegrater Mac Pro tower. Fingers crossed.
