50MP would be an interesting number.   I'm guessing this would be about 
a 5 micron pixel size- which may be just a bit too small for really 
low-noise pixels unless something changes.   I don't think you'd want to 
get smaller than this.

Calculation:

sqrt(50E6)=7kpixels/side
30 ave mm per side
233 pix/mm
.2 pix/micron
5000nm/5 micron pixels

If my math is wrong, feel free to point it out.

The point being, this is not going to be like computers where we've gone 
literally a 1000 magnitudes in a few decades.    We've got less than one 
magnitude of image sensor capability left in a 35mm system.
