I meant that I have seen picutures from Sony cams using the two sensors with the same exposure (I believe posted by dpr member RicksAstro). They were very similar. The quantitative measurements at DxOmark from a55 and a77 also seem to indicate that they would perform essentially the same and it does seem that the read noise is somewhat smaller in the a77 from your own sensorgen figures? At least in Sony's implementation of the sensor.

Actually, the Sensorgen figures show that the read noise of the 24MP is lower than the 16MP (about 2.5 e- per pixel as opposed to about 3 e- per pixel), which would make the 24MP about equal integrated read noise, as you suggest. It looks like my memory is playing tricks here. So, even that exception to the rule goes.
