I'm talking about full frame high-end professional cameras (the ones where the 
body with no lens costs $8k or so). This has been consistant for over a decade. 
So I don't think it's a cost/manufacturing limit in place here.

There are a lot of cameras made with smaller sensors in similar resolution, but 
very little at much higher resolutions.

at the low end, you will see some small, higher resolution sensors, but those 
are for fixed lens cameras (like phones) where you use digital zoom
