I love the way the ZorroIII figures go up every year ... by 2010 it'll be up to 10Gb/s ;-)
I think you'll find it is a case of PCI being a newer design/implementation than ZorroIII (late 80's early 90's vs late 90's)
There was "discussion" (actually fanatic ranting) about how the ZorroIII bus was better than PCI, think the conclusion was that ZorroIII could scale up better if a decent chipset was made.
In the end which bus technolgy won out ? Which has the best support ? ... not hard to answer.
