I'd love for Apple to bring back the Mac Pro, but Apple hasn't had an affordable Mac Pro tower since the 2012 model. Apple got rid of the tower in 2013 in favor of the "trash can" model. When the trash can languished for years without updates due to limitations with its design, Apple brought back the tower Mac Pro in 2019, but at a dramatically higher entry MSRP, which priced out many users of tower and trash can Mac Pros (I have a "trash can" and was very disappointed by the 2019 Mac Pro's entry MSRP). The introduction of the Mac Studio revealed a large price gap between similarly-specified Mac Studio and Mac Pro models. Given the lack of expandable RAM in Apple Silicon Mac Pro models, and also given the lack of support for NVIDIA GPUs in macOS, there weren't a lot of customers for Apple Silicon Mac Pros when the Mac Studio was available at a lower price, and thus the Mac Pro got discontinued.

In many ways, the Mac Studio is the spiritual successor to the trash can Mac Pro. Apple Silicon's architecture solved the thermal problems that limited the trash can Mac Pro.
