No one "needs" a raw camera. But everyone wants good quality. My guess is that the shows that use the D21 rarely records through a Codex. I would bet that most of them are recording to HDCAM SR. For convenience and safety. I would love to hear Mike M comment on this.
I know D21 stuff being recorded @ rec 709 to prores 422 on a KiPro....
