I stopped by the Casio booth here at Macworld and played with the Casio EXILIM Pro EX-F1. It's still in the final stages of development, but they should have a full production model ready for testing by PMA. I have an appointment with Casio there to test the latest version.
I'm excited by these specs: 60 fps still photography, CMOS sensor, DNG format, 7 fps burst mode with flash, HD and SD video, external mic jack, and tons of other goodies. This camera is a true speed demon.
I'll report more after testing the finished model in Las Vegas, but I wanted to get it on your radar now.
