That Mac Pro probably won't include a new chip though since they said "one last chip" when presenting M1 Ultra. So no more than 128gb of HBM, but maybe there will be some kind of DIMM support?

I assume they will do 2x M1 Ultra. There are limited quantities of LPDDR5x with 64GB per package. That is 512GB for M1 Ultra, 1TB for 2x M1 Ultra.

I think and assume they will continue to stick with LPDDR5 rather than standard DDR5 with DIMM slot.
