One problem that I’ve seen with using Firewire for live switching is that it has such HIGH latency.
For most professional projects, the latency is why they don’t use firewire cameras. Also you are limited to short camera cables with firewire.. Not a chance of doing a quality multi camera sporting event, play, etc with firewire because the cameras have to be so close to the computer.
Just a few more things to consider when making your decision.
