5 MP 0.6" microOLED for your EVF anyone? Given optics that could place the apparent image at the right place (like on the focusing screen? like the LCD in the 7D), this would exceed human acuity - it would only need to be fast enough to be imperceptibly delayed and it would be a huge leap forward for the DSLR - "almost life-like" display with overlay all the ancillary info, live histogram, zoom level selectable etc and a brightness/visibility that didn't require fast lenses or much light at all (think exposure simulation). A mirror would still be needed unless contrast (as opposed to phase) AF gets much faster, but the clunky prism not so much
Not too much longer to wait - maybe.

I would love to see this post 5 years from now.... I suspect that they will both exist for a long time together, but eventually the optical VF would be replaced once the display technology get significally better. Many motivations for it including not needing a shutter mirror, a prism . Im not a pro, but as a hobbyists, I can see it disappearing from entry level cameras in 5-10 years.
