I wonder how hard it really is to build even the simplest VF into a camera these days. The EP-1 is not a tiny camera, so it seems there was a deliberate design decision not to include one.
I really don't see the sense of optional VF's (or powered EVF's for that matter). It seems like such a backward step considering they managed to figure out how to build them into the cameras 50 years ago (and that was with a lot more stuff inside the camera).
We might need to remind ourselves that we are not necessarily the target market. A good friend of mine here at work is buying an EP-1, not because he is a RF fanatic, but because he likes the retro-look and thinks it looks cool.
