Keith,
Physics is what happened. When one stands the same place with a 24 X 36 mm and an APS-C camera, they will make the same photograph unless the thinnest possible DOF, ultra-challenging dynamic range or extremely low-light levels become important.
Initially the difference in the sensors' analog signal-to-noise ratios was a compelling reason to move to a 24 X 36 mm camera. The increased surface are yielded a distinct and noticeable advantage.
Today, APS-C CMOS technology outperforms the top performing 24 X 36 mm systems from just a few years ago. This data compares the dynamic range for a large number of camera. Dynamic range depends almost entirely on the SNR of the camera's data stream.
Of course many of the current 24 X 36 mm sensors still have a higher SNR than APS-C systems. But now that difference is much less limiting than before.
People have the option of trading weight/size or user interface differences for a relatively small improvement in SNR. Most photographers deal with weight/size/enjoyment of use issues everyday. They may require the extra stop or so of dynamic range/SNR on rare occasions. With optimum exposure technique, the shadow region SNR of APS-C CMOS sensors in no longer a concern. It's good enough™.
Nikon and Canon let their user experience remain stagnant. Only recently have they responded to challenge of APS-C and m4/3 systems. Nikon still refuses to market a D300 replacement. Canon still uses inferior analog to digital converter technologies. SONY has responded well, but I'm not sure they even sell DSLRs anymore. I haven't read about one for a long time.
