Well, maybe also better in low light.

 

Only if you don't care about depth of field. And the existence of the metabones speedbooster also takes away some of the arguement for mainstream full frame. I'm not optimistic enough that full frame will ever be cheap enough to be mainstream. It will always be higher end proposition for those who need and really know what to do with it.

 

As for the old MP debate, we're still nowhere near the limits of technology or laws of physics yet. When I last did the calculation a few years ago, if you scaled up a P&S camera sensor to APS-C you're already in the 100MP+ ball park. I hate to think what the number would be today. As long as we have the bayer filter, I think it is desirable to go about 2x linear (4x area) sampling over what monochome physics say is optimal so as to preserve colour spatial accuracy. And if the lens is guaranteed to be the limiting factor, you can safely ditch the AA filter from the start.
