A mirrorless camera cannot be operated in OVF mode. Sorry, but MILCs are downgraded DSLRs with surgically diminished functionality.
At least that's how I see it.
A DSLR could do some of the fancy tricks "just like a mirrorless", with the AF games and such. As we all know, once the mirror is up, a SLR is mirrorless anyway...
But they probably won't, as once you implement all that on-sensor stuff at a top-of-the-line form, adding a mirror, optical viewfinder, separate focusing system, and separate meter is expensive and way behind on the law of diminishing returns.
I also don't think anyone has yet mastered the art of blending an optical viewfinder with an electronic one in a seamless fashion, and until that happens, there will always be a moment of weirdness when the changeover happens...
But while we'll probably never reach feature parity on all of those features the mirrorless folks go on about, for the time being, there are still plenty of DSLRs, and those of us who like that sort of thing can keep on using them...
