All very expensive cameras. I believe doing great very expensive cameras is much easier than making good cameras at a great price.I'm sure the Olympus is a great camera, but very pricey and of a doubtful value.
I can't tell if this is going to be a successful system or not but I can find a few problems and I don't agree that the smaller sensor is an advantage or even a good move.Some problems:Design - I like it but is very "industrial", don't seem made for the masses.
Sensor size - too close of the compact cameras that can fit a 10x zoom, and are smaller, cheaper and .... eventually with less IQ... will people care?!
Image quality - Nikon is probably the best in their DSLRs but with a sensor of this size they will lag behind.
Timing - too late, Sony and Olympus are leading the way.
Compatibility with DSLR system - put the adapter you want, with a 2.7x crop factor, just seems wrong.
Versatility - People that want a bit more than "point and shoot" knows that DOF control is of great importance.
A flop? Probably.
