One thing to keep in mind is that stills cameras suffer the same "resolution loss" that we are talking about here for the RED One or other bayer-pattern sensor systems. They just don't advertise this. In fact, most like to advertise the full "megapixel" count of the sensor even though they rarely record that. As a quick example, the Canon 7D has an 18.2 megapixel sensor, is advertised as "18 megapixels" and actually gives a recorded image of 17.9 megapixels. With a nominal resolution about 18% lower than that.
I think a lot of stills people are blissfully unaware of how their sensors "see" the image they record. And most stills cameras do a significant amount of internal processing to that "RAW" image as well.
