I've always maintained that mirrorless cameras will eventually make OVFs obsolete, as I was certain that technology would eventually remove all disadvantages, leaving only advantages. Certainly, Panasonic's LVF-1 was not helping my case, but even the G1's built-in EVF and Olympus VF-2, while nice, were a long way from making that dream a reality. The increased refresh rate on the GH2/G3 do a lot for tracking action in bright light; not so much for low light. However, they still feel like you are looking at a TV. In steps the current generation Sony EVFs. The higher resolution OLED display should definitely improve the real-life feel. I also believe the refresh/processing rate is faster. So, the question is: are we there yet? If not, what still needs improvement? I don't know if/how much it slows down in low light, so that certainly could still be a concern.
