Don, I agree, the bulk of their cameras are mirrorless, because they're compact cameras.
However, I happen to like looking through a mirror and pentaprism. Not that this is a fair comparison, but are electronic viewfinders going to replace the roof prism in high end binoculars too? Last year I compared a lot of them, they're all a little different. I didn't buy any of the "alpha class", but I did compare them. One of the ones I bought was a lot cheaper, and actually had more contrast than a Swarovski...however it was the 2009 Swaro, and not the new one...they didn't have any new ones.
Regarding the Olympus, I do find that interesting. It is the same size sensor as 4/3, the "2x crop" with 4:3 aspect, right? Like, at what ISO settings did it pull ahead of the 7D, etc? I'm certainly not trying to say the 7D is some kind of mountain king...I don't even own one myself. However, if the price for a new, non-refurb body somehow falls to the $700 range, I might succumb to buying one...regardless of whatever other FF body I decide on (I need to sell at least one pair of bino's, and a small telescope first).
I admit, the new Olympus body looks cool. I once considered trying to study industrial design, back before all my dreams were crushed, and half my life got wasted away. Also wanted to design "the next Porsche". I dreamed pretty big as a kid. They did see my design...I sent it to them. This was 1989...I digress again. I guess I'm just citing an example of using imagination. My dreams weren't very realistic, but I took the chance anyway.
Oh, and regarding other unrealistic dreams...I mentioned in another thread, about my dream lens. Some kind of really fast zoom, like a 60-115 f/0.8. Maybe it's not even possible to build something like that without severe aberrations and vignetting...but what if it were possible? Of course, it would be expensive. I just...would absolutely love to shoot shallow DOF wildlife at sunset with something like that. A companion lens could be a fixed focal length, 165 mm f/1.0...
