Death to P-TTL (and other proprietary flash protocols)

But it appears the interface and implementation AREN'T separate. Maybe this is why it takes a very long time for Metz to produce a firmware update for a single camera.

My previous point is it may take a common camera control protocol across manufacturers before a common flash protocol becomes feasible. Who sees that happening?

Every camera manufacturer uses different logic to drive their cameras and that's before we even think about flash photography. Adding flash, you create an interaction between camera and flash unit that's going to be independent among manufacturers simply because each camera is different. Therefore, trying to drive to a common flash protocol may necessitate a corresponding drive to a common camera logic, too. At that point, what's the difference between Canon, Nikon, Pentax, etc.?
