The same holds true in digital imaging systems, the transducer and analogue to digital conversion then the subsequent analogue reconstruction and output of the digital data sets the system performance limits in a well designed system. Even consumer film scanners are near the practical limits of film resolution now at 5400dpi, any more resolution and they will be capturing film grain detail with accuracy, not more actual image detail. Of course it's more difficult to construct a direct digital capture camera and the current products aren't as good as film when appropriate tests are executed. However they will eventually become as good and then soon after better than film in both quality and cost at which point it will be interesting to hear the arguments from those film proponents that seem currently so opposed to digital image capture.
