Some pretty wacky mounting stuff. I just bought the 'head strap' mount - it looks really stupid, but it's perfect for driving POV shots. Given enough light, the camera image is great -- plus it has a superwide lens for that real POV feel.
They had some dynamite demo sports footage at NAB.
I've been converting the files to MXF in Vegas (and burning them to XDcam Pro Discs with a U1 drive) for my clients who use the XD disc system.
