I could be wrong...but I'm pretty sure that the PCI bus runs at half the speed of the frontside bus, which until about 18 months ago worked out to be 33Mhz. Currently, we see some MB's with 133 FSB's, therefore in theory their PCI bus speed is 61.something Mhz. I guess that many hardware vendors still develop cards at 33Mhz to ensure backwards compatibility. So, PCI buses are getting faster. And yes ISA does suck and I hope its being phased out.
