And if we could ask for a more radical change, extend the range to 24mm.
The Ricoh GX100 does not convince. The current bridges have pathetic sensors.
More radical would be to put the S5 sensor in it (hell, the body is plenty big enough), include in camera CA processing like the new D300/D3 Nikon's do.
I think in another 5yrs, 'bridge' cameras will become obsolete, or a tiny niche market. Compact PnS will offer enough range and performance, Ricoh's Capilo R6/R7 while not great have 28-200mm lens, and soon there will be a Nikon D30/D20 series that cost the same as the 6000 does now(body only), with newer dSLR 18-250mm 'compact' zooms from Tamron/Pentax adding OIS in the future, bridge cameras will make less, and less sense.
Ever improving compact, pocketable, PnS; combined with lower cost dSLR's will cause the market for bridge cameras to buckle & collapse, IMO
