Lots of interesting points epixx. But I don't think that C and N are waiting for Sony's solution. Even Sony will be/is the first offering a suitable EVF means not that that's is the best quality solution.

Interesting also your point reg. the mechanical shutter. I personally would miss the 'click clack'. When Porsche switched their engines from air to water cooling 10 years ago they technically managed to have the same typically Porsche sound as before.
