3) FF camera with a fixed lens for around $1G. Who wouldn't want an excellent image quality in a small package like this:

Well, there is a reason not to make a camera like that. It would be packing a very expensive FF sensor. This lens is an f/4.8-13. You could get exactly the same results building a camera around a Four Thirds sensor and an f/2.4-6.5 lens (provided you shifted the base ISO to 1/4 of the FF camera's base ISO). Such a camera would be smaller, much cheaper and the results would be indistinguishable. Coupling a slow zoom lens with a FF sensor in a compact camera just does not make sense.

With FF design you are trading the cost of the sensor for the cost of the lens to provide equivalent designs with the same parameters: lens has to be 2x faster, it's resolution, tolerances 2x better. Provided the cost of sensor is going down and the cost of lens manufacturing is likely going up, at some point FF design will be more cost effective even in this case: silicon eventually beats the metal.

I think in this case a 19-85/2.4-6.5 lens and an FT sensor would be a smaller, cheaper and better solution. Such a lens is not really exotic, would be quite cheap to manufacture and the sensor would be far cheaper.
