Thxbb;
I think what Jabez02 meant was if a 36MP user was getting 12PMP of resolution out of thirty six (which is easy to achieve: reasonable zooms get 15) you would expect far fewer PMPs our of a 16MP sensor. And indeed the very best M43 lenses on M43 sensors seem to get 8-10.
None of that says that you *need* more than 8-10PMp; I used to have an 8MP camera once and I imagine the lens/camera system was probably getting 4PMP and it seemed fine. The point is just that even holding fixed the greater importance of blur, the difficulty of designing lenses etc. the more more MP generally the more PMP in the result, even if often not much more.
But of course I agree few need that; there are other reasons for choosing between systems than resolution.
