For many applications, yes. There will always be a segment that prefers an optical viewfinder, though of course they could make the camera mirror "optional" to please everyone.

The primary "forthcoming" technologies are better EVF and focal plane phase detect autofocus (I'll call it "FPPDAF"). The latter is already completed in the Nikon One -- all they have to do is get it working on larger sensors (if any significant rework is in fact required). The former (EVF) is going to take while.

It's much more than that. They will be capable of frame rates that DSLRs have never even heard of. Autofocus that is faster, more accurate, works in less light, covers more of the frame, and never out of collimation. Wide angle lenses that are faster, cheaper, *and* optically superior. The list goes on.

I can't wait for the mirror to die.
