Chinese site M.I.C. Gadget has thrown in its own list of possible improvements to the next version of the Mac Pro, now more believably expected to turn up at or around Apple's Worldwide Developer Conference next week. This list of specs may be just educated guesses or based on genuine leaks, but mentions support for SATA 3 and SAS connectivity with native support, which would facilitate more uses of SSD storage. PCIe 3 is also postulated, along with Thunderbolt, USB3 and Intel Xeon E5 processors.
