You might remember Casio's EX-FC100 and EX-FH20 as two Exilims capable of 1000fps slow-mo video. Both 9.1-megapixel cameras are getting a 10-megapixel CMOS sensor, and the FH25 (a 20x superzoom) does 40fps high-speed bursts at 9 megapixels (up from 7).
Everything else on the EX-FH25 looks to be the same. Similarly, the EX-FC150 will keep its 5x optical zoom, and sensor-shift image stabilisation. Both cameras will continue to do 720p video at 30fps.
