Those are all good wish list items.
I have been quite impressed with the image quality of the 1/7" sensor, over the 1/2.3" sensor in the Q and other contemporary models. If they put in a larger sensor, the zoom range and/or aperture will suffer unless they put an even bigger lens in. So for me it's a wash. Personally, I don't need such a wide-ranging zoom, so if I had to choose between two of the three, I would go for a slightly larger sensor and fast lens, and give up some zoom range.
Originally posted by Biro ... how about an optional external EVF for the hot shoe?
Well this brings up another point, that it would be nice to have a hot shoe to begin with. I would probably prefer a hot shoe over an EVF,
if I had to choose between the two.
JMO, I generally agree with your points.
