I can't speak for errett, at least not to the specifications of the studio cams, but as I am an editor and also do playout, and I can say that there would be a whole lot more work than just changing a setting on the camera in order to do Fox 16 News in widescreen. All the graphics would have to be redone, and a major upgrade, if not replacement for the editing systems. I'm not sure if ENG cameras have a widescreen mode or not, but they are DVCPro, so they are not HD. Now, I really wish that the guys putting this stuff together 2+ years ago had considered all this, and we could have gone HD from the start, but unfortunately, I don't see it happening now.
Anyway, having said all that, E is the engineer, and he may know some stuff I don't.
