Olympus's E-M1. If they've done this right, it's a clear challengeto the DSLR

    If the phase on chip focusing works fast and can provide a decent AF-C mode, this is an example of why the traditional DSLR with the mirror will die. I can't imagine Nikon or Canon continuing to almost 100% stick to DSLRs over the next couple years. Aesthetics aside, once you've used a high-resolution electronic viewfinder, the limitations of optical viewfinders become glaring, most obviously in dim lighting or complex MF situations.

    It's slower when phase focusing though, but still plenty fast.

    So the idea here is that you'll get (in the future, when mirrorless owns
    DSLR) a super high definition EVF that has as fast AF as any DSLR due to
    phase trickery (i.e. not contrast focusing) and give the user the
    benefit of the future EVF in terms of low light performance?

    Maybe, but that has got to be one high def EVF, I tell you. And also -
    how do I benefit from it directly? I mean, some MF matters can be dealt
    with by using a handy 1:1 zoom button somewhere on the camera, but would
    I also have a "boost light" button for the EVF? I mean, because the
    default view should be 1:1 what the sensor will record, right?

    I haven't used a EVF for ages...

    Gain is automatic. Point a new EVF into a dark area, the area lights up. Ultra high resolution isn't strictly needed in an EVF for it to perform better than an optical viewfinder on subjects. A magnification feature (2-7x)allows for much better manual focusing than any optical viewfinder. I've done the tests on this. Focus peaking (though I haven't test that feature for accuracy and "focus resolution") is another thing to assist in manual focusing. Lastly, the elimination of the mirror slap of a DSLR is a boon when using long focal length lenses, macro lenses and anything else that requires steadier than 1/focal length shutter speeds.

    So, the EVF won't show me what the sensor will record, then? Well, that
    sucks.
    I disagree.
    Sure, but if I'm looking at pixels through the viewfinder, then it's a
    no sale.

    You prefer having a dark viewfinder in manual focus mode?

    The lightening up is only when you try to manually focus.

    That's not what Rich said though. I asked if it was user-selectable and
    he said it was automatic. If it's automatic only when in MF, then it's
    more ok.

    I'd still want to have a boost-button that I can select myself, since
    one of the points of an EVF is that it can show you what the sensor will
    record, as opposed to a normal viewfinder.

    But I'm assuming that when it is in gain mode, it will show me a
    exposure meter in the viewfinder?
