Nikon mirrorless? Sony NEX-7 is rangefinder copy? E-P3

Lots of buzz everywhere about a new Nikon system with a sensor halfway between a compact and m4/3.

Quite why Pentax and now possibly Nikon are going down this small sensor interchangeable lens sytem route is beyond me. Where the market is I'm unsure.

SonyAlphaRumors are saying that the above mock-up is being rumoured as what the NEX-7 will look like. 24MP, Viewfinder etc.

Finally Park Cameras rang up to say that one of these is apparently on its way to me today.
