The Samsung booth has some really amazing video cameras coming out. The one that really caught my eye -- the SC-HMX20C. First, it's quite small. Far smaller than my current camcorder (it weighs less than 1 pound). Secondly, it uses flash memory for storing video and will accept external flash memory modules. And third, it records at 1080p.
One advantage it has that other high-definition cameras do not have is that it records natively at 1920x1080 as opposed to a 4x3 ratio that is than extrapolated to 16x9 resulting in higher quality video.
A feature that video enthusiasts can appreciate is that it supports up to 300 frames per second allowing for very high speed recording. Imagine recording your kid's baseball swing in fluid slow motion. It includes 8 gigs of flash memory.
The Samsung people tell me that it should be generally available in May 2008.
