I expect that expansion cards from Apple are going to be the way they differentiate the mac pro line. I'm betting that Apple is going to come out with discrete GPU's based on their integrated graphics and sell them as add-ons for the Pros for ML/AI workloads and likely to help with normal stuff like rendering in Autodesk/Adobe/Finalcut type apps. That said, it isn't the bet I'd make if I was tasked with purchasing for a company. I'd get the studios in a reasonably high config and then sell them every 2-3 years and replace with newer model. You'd pass the pro's in perf pretty readily from CPU bumps alone and likely recoupe a lot of your investment.
