Exactly. We currently grab 3 rgb pixels, average them out and arrive at a bw average value. A bw only sensor could well put us in the S2 range. The extra pixels might well translate into more sharpness, contrast, etc... not to mention iso. If this fantasy came true, there'd be no doubt that digital had finally beat out bw (scanned from film or otherwise).
