Oh I'll put my money on PCIe slots in he new Mac Pro... I expect that to largely define the "Mac Pro". Lots of folks want PCIe slots, for storage and options cards not just HDX cards. I mean how are you supposed to get 400 Gbit Ethernet into one of these boxes ¯\_(ツ)_/¯

PCIe hanging off a chip stuck between the Ultra chips? Or a variant based on a M2? But will it be PCIe 3? 4? 5? (better be at least 4) and how many lanes???

And yes then having PCIe slot to M.2 adapters will give gobs of storage performance. Eagerly waiting on seeing what is announced at WWDC.
