Except for the fact that the only reason behind the SLR has to do with allowing the photographer to view the precise same image that will be recorded on film...

The digital SLRs may well use the flip-mirror SLR system (I belive some do). However, given the current state of technology, why not just eliminate the moving parts and allow the photographer to view the same image received by the CCD, either via an LCD on the camera back or a view of a duplicate through the eyepiece.

Still, if someone wants to be a purist, I suppose a true SLR flip-mirror design might be in order, allowing for a non-pixellated view of the scene that corresponds with the maximum resolution of the human eye just prior to the shot.
