Actually I have to revise the opinion I expressed at the LAC talk. There are scenario's where firewire might even provide better latency than PCI. I think the lowest latency achievable (at the interface side) is approx 32 frames (i.e. 2x16) which is quite comparable to PCI I guess. The problem is the extra latency added by the device. This can be high, but for some it is very low (e.g. 16 frames). To summarize: a total roundtrip latency (jdelay) of less than 100 frames is achievable with firewire. A delta1010 has approx 180 frames (if I remember correctly), so I guess firewire can be competitive.
