It depends on how the sensor is designed. Quad Bayer consolidates its data to improve low-light and save on file sizes but ... that's why there may be a separate videocentric S model on top of a jack-of-all-trades.If the next gen of MFT camera uses a chip with this many sites, doesn't this essentially doom the camera's chances for being better in low light? I don't know what effect, if any, it'd have on dynamic range..
With GH-5 being heavily discounted, it's possible the GH-6 announcement is right around the corner.
