Sports cameras do it all

Full frame sensors can be useful as they offer better control over DoF (depth of field), and as far as dSLR's go, give you access to proper wide angles, though of course, new-breed mirrorless cameras are changing the playing field. As for image quality, I'd agree, especially with sensors like the X-trans by Fuji, the need for full frame in today's market is debatable. While smartphones will kill off compact cameras, I think m3/4 will eat into the sales of dSLR's.
