Suppose there will be a choice for two versions of the camera, old (with old hardware, just a guess) and new (with newer hardware) as at other manufacturers. But, if we look on firmware numbers of our own camera we see that and now we have different firmware.
But that's all right, development and testing takes time

Thanks on info
