The fact remains that the limiting factor for resolving power is the LENS, not the film or the chip. Modern films, both black-and-white and color, can resolve detail to the near molecular level. Even the best prime lenses for 35mm/FF DSLR can only resolve 125 lp/mm. Film is capable of greater resolving power than that- Velvia is capable of resolving 160 lp/mm. A 35mm Velvia transparency is the equivalent of a 22mp sensor. So unless you are shooting some medium format lens (with a resolving power greater than any known 35mm lens - (not going to happen - no MF lens resolves higher lp/mm than 35mm lenses do) on a medium format image chip, the current state of the art is not going to have a digital file out-resolving a film negative. Even if you have more pixels crammed on the chip, the limiting factor is the resolution of the lens.
