It appears that Canon is continuing R&D into some kind of hybrid viewfinder for DSLRs. Canon News has uncovered a recent Japanese patent application from Canon for a hybrid viewfinder.
Patent Summary:
This one is a clever application where the EVF moves up with the mirror, to show the EVF image through the viewfinder.
This one has some real potential for implementation; as the entire optical path for the viewfinder remains the same for EVF and OVF operation, eliminating what would be a far more complex bulk on top of the camera as the last hybrid viewfinder patent demonstrated.
