The Leica M8 has a 10MP sensor in a 3:2 configuration resulting in a pixel image of 3936 x 2630.

A hypothetical 60MP MFDB sensor in a 4:3 configuration results in a pixel image of roughly 8944 x 6708, but to compare apples with apples, I will make it the same 3:2 configuration as the M8, or 9486 x 6324.

Now, let's say that the British Museum calls you up and asks you to do some important copy work for them. It involves photographing some artifacts of size 10cm x 10cm. For simplicity, let's just look at the longest dimension and a single image capture. And, to compare apples with apples, we must assume for each camera that a lens and shooting distance are used so as to provide the same field of view and depth of field.

If you took your M8 to do the job, you would be taking 10cm of the information and distribute that over its available pixels of 3936, giving you a resolution of 3936 / 100mm = 39.36 p/mm = 19.68 lp/mm.

If you took your 60MP MFDB to do the job, you would be taking that same 10cm of information and distribute that over the much larger number of pixels, namely 9486. This would result in a resolution of 9486 / 100mm = 94.86 p/mm = 47.43 lp/mm, or more than twice the resolution of the M8.

This MFDB will always provide higher resolution images, up to the limit of the lens. Only above that limit (which can be up to 250 lp/mm for some MF lenses), will the M8 begin to yield higher resolution. However, this will only occur at the macro scale, never at infinity.
