How do you want Fuji to respond to Pany FZ200?

Let's assume Fuji keeps the manual zoom, which most people see as an advantage. How should Fuji answer Panasonic?

XS-series with constant aperture, same zoom range, current 2/3 sensor size, probably requiring larger camera?

XS-series with constant aperture and shorter zoom, possibly needed to keep current size?

XS-series with 1" sensor, current zoom range and floating aperture?

HS-series with same size sensor as FZ200 and constant aperture?

There can certainly be other combos, but I chose these 4 because the big news about the new FZ200 is the constant max aperture.
