I wonder if this puts to rest any ideas of a refreshed Intel Mac Pro, or if it's now completely done and just waiting for the AS Mac Pro.The next Mac Pro would definitely be Apple silicon. The 2019 Intel Mac Pro will be obsolete in 3-4 years.
From seeing the supposed M1 Ultra performance, I can see how a Mac Pro that ticks a few extra boxes (Like PCIE slots or some expandability) will completely make the Intel Mac Pro unnecessary.
We'll see, maybe WWDC in June?
