I think the most interesting thing is the 4K camcorder, (not that I'm planning to buy one...)
They've also announced a new version of the Action Camcorder, the HDR-AS30V, which adds 1080p 60fps video capture to the range. It's expected to be available by the middle of the month for $298.
They've also announced the HDR-MV1 Music Camcorder (no price and no delivery date.) It's an interesting looking duck, but I think I'd rather get the mic away from the camera, no matter how good the mic might be.
