The MicroOLED is an expensive offering for medical, industrial, military applications etc.
And then it isn't nearly as good as it would be required to rival an OVF.
E.g., its 1280x1024 resolution needs to double to become true HD (1920x1080), the currently accepted standard for a sharp display. Personally, I expect this to go up to about 3.3MP, based on what the human eye can resolve, even more when comparing with an OVF with a wide field of view like in a Pentax MX.
Contrast is reported 100,000:1 or 16EV. That would
just meet my spec if the display controller drives it with 16 Bit. But that's not the case, the actual contrast is very compressed and has a lot of shadow noise in live view because only a subset of pixels is read out and are noisy at 1/60s which is as good as it gets at 60p. Moreover, all the cinema going on in an EVF makes it impossible to display a scene with its original contrast which means that a lot of detail remains unvisible. Like a face besides an open fire, or the mentioned polarizer effect on the sky, or a starry sky etc. ... So:
- Price competive to an OVF: no
- Resolution competive to an OVF: no
- Contrast / dynamic range competive to an OVF: no
- Responsiveness competive to an OVF: no
I didn't even talk about the latter. Even at 60p, the lag is noticeable with current EVF, the processing pipeline is too slow. It is slow enough that you cannot frame a bird in flight with an A77 and a long tele. My estimate is that everything above 20ms lag is too slow to rival an OVF. The current lag is more like 5x this value. I really would like dpreview to measure lag, which is easy by photographing a camera looking at a rotating disk (at 100rpm) with both disk and live view display visible on the image.

Yeah, only the best marketing can attempt to release a new product in a way nobody takes notice
