I'm clueless, that's why I was asking. I do note that in this video http://www.youtube.com/watch?feature=player_detailpage&v=fEm8h7T8-lY#t=206
it states, in the context of "clean hdmi" video output, that "the camera shoots raw." Now that really makes no sense if they have suddenly flipped back to talking about stills.
DPreview says that they "were told"
"In addition, the camera's footage can be output over HDMI, either with settings overlays for monitoring or without, for recording (and, we're told, with the option for uncompressed 4:2:2 video output)."

Which would be something rather new.
