Unless there is a change in technology. once you get above 24 MP with m43 sensors then I suspect that things may fall apart on you. Sure you have 20 MP 1 inch sensors but I don't usually go above an EI of 400 unless desperate. Do you want to be limited to EI 400 - 500 ?

 

Probably better to tweek the sensor,processor,AF and exposure performance than go for broke. Perhaps not as sexy but the boys in PR should still be able to sell a 20% improvement in AF speed and accuracy. If not then they should be back to copy and pasting the second hand car ads.

Hey, I wasn't advocating higher MP M43 sensors; just saying that if they happened then the low ISO resolution of the Only12-40/sensor combination might be greater than the current system resolution of FE2470/36MP. Whether that would be worth any tradeoffs is another matter.  Having said that, it seems these days that overall sensor size (rather than no of megapixels) that determines high ISO limitations, so it might not make much difference. That is, it's not the pixel density of the I inch sensor which limits it, but it's size (unless of course you are looking at non-normalised 1:1)
