GR Digital V has an APS-C sensor

Even more so the lens size. Even if they made the body NEX size, the 28mm on the GXR shows how large the lens has to be for an APSC sensor (and even then without the macro capabilities of the current GRD 28mm) as well as non-telescoping makes it non shirt-pocketable as the GRD is.

I just can't see it happening because it would turn the GRD into the GXR 28mm, so why make two 28mm APSC cameras the same and kill the whole notion of the GRD. It makes no sense.

A 1" sensor in the GRD is inevitable and it can keep a telescopic pocketable lens. For those who want an APSC sensor camera with a non-telescopic 28mm lens, Ricoh already makes one anyway. Why do you want them to turn the GRD into the same thing?
