Who wants to sell half-frame if you can sell full-frame?

lots of companies, because the cameras can be manufactured for less and
sold for less.

Sony don't sell many full-frame cameras compared to Nikon and Canon,
while market share of FF vs APS-c and u4/3 must have increased
dramatically, Sony have poured billions in to their sensor division.
It would be interesting to see a breakdown, I'd guess that
interchangeable lens camera sensors aren't what's driving production
capacity increases, but phones, go-pro type devices, security cams, and
just about any other device that's going to be part of the "internet of
things" where some imaging function could be useful.

There's plenty of other makers for APS-c and smaller imaging sensors.
Nikon isn't tied to Sony, Canon and Samsung can make their own.
Doubtless the
cameras and lenses for full-frame will bring in more profit.

not necessarily.

And the
designs mostly already exist.

not really. the old designs are outdated. newer designs are *much*
better, the nikon 14-24mm being a good example.

For lower-price FF wide angle zooms, even a "budget" made in China
Nikkor 18-35 AF-s performs much better (resolution etc) than any
approximately equivalent field of view zoom on smaller APS-c or u4/3
formats.
