Thinking about the thread a different way, I do think a Intel + PowerPC G5 would’ve been a cool Mac Pro during the transition. Even though Rosetta took care of it, having a dedicated PPC processor wouldve been a cool idea then. Similar to the Xeon PCIE Co-processor(e.x PCIE G5 processor?). Would be useful to the heavy PPC users that have not had their software update to support Intel probably. Then would be phased out in Mac Pro 2,1 or 3,1.
