That's possible- I dont see a high likelihood of a new HS series model, it seems like Fuji is moving on with it's new "S" "waterproof" series.... it's just that the term "point and shoot" seems misleading because of all the customization available with these cameras. I thin Kim and a few others have shown that in bright light and low ISO, it's hard to tell the difference between the output of these cameras and that of a large sensor camera. DR is on par with a large sensor camera too, it's just the ISO issue once over 400, these cameras are left way behind. I'd just come up with a different name, I guess superzoom is as good as any, it pretty much describes what the camera's main focus is.
There are actually some niche markets where smaller sensors are much preferred over large sensors- one is then extreme zoom market (for portability and the cost of having to buy extra lenses) and the other is digiscoping. Because of the way aperture is calculated, small sensors are actually more sensitive to collecting light than large sensor cameras are when part of an afocal digiscoping set up. DOF is much shallower for a given aperture with large sensor cameras of course (this may be a positive or negative depending on taste and type of photography), but exposure times are shorter with the smaller sensor when afocally digiscoping. The large sensor cameras need to use higher ISO to compensate. Another area in which small sensor cameras may be better is close up macros. You'd have to spend a lot of money to get a large sensor camera that could match the great macro ability of some of the venerable 'P/S' cameras of the past. In pretty much everything else, large sensors are better.
