There will be 3 new Fuji cameras announced around September this year. This tweet from the Fujiguys back in February also indicated something "exciting" coming in Fall '11:
Here is the rundown of the rumored new Fuji cameras:
1. The first camera will be a large sensor (maybe APS-C or m4/3rdsish) fixed lens hybrid with a 20x zoom and weather sealing. Fuji is targeting the low enders who might otherwise get a Nikon D3100, but don't want to buy a system camera.
2. The second camera will be targeting the Panasonic LX-5/Canon G12 crowd. It will be a fixed lens compact, with a f/2-2.8 aperture zoom lens, and retro styling. It might have a viewfinder but this is not confirmed yet.
3. Now it gets interesting: the third camera will probably be some kind of a mirrorless solution with a sensor probably smaller than APS-C, something in the m4/3 range. Just a reminder that Fujifilm is part of the Micro Four Thirds System Standard Group.
There was another rumor that the Fuji X100 is just a stepping stone and a X100 based camera with interchangeable lenses is expected in the future.
