In the planetary cam world yes. In the astrophotography world Sony has several generations of sensors to catch up to the old Kodak chips. Sony seems to specialise in small sensors. Funny that when the Nikon D800 has a full frame 36.3mp CMOS chip that is state of the art and Sony has at least one if not several full frame 24mp chips (Nikon D600, Sony A99, Sony RX1). I have yet to see a Sony chipped based camera image that comes close to a good Kodak CCD image.
Also there is a question about Sony QE values. These are not apples to apples comparisons with Kodak measured QE. Its a game of definitions.
The Sony chips may not be anymore sensitive.
I look forward to seeing some of the True Sense chips showing up in astro cams. These are one shot colour but with a clear microlense instead of 2 green. So its an LRGB matrix rather than RGGB. It is claimed 2 to 3 times more sensitive to light as a result. Could breath some life into one shot colour cameras.

the QHY12 OSC with a 14.2m chip, 55% peak QE and low noise is also a very interesting development that seems to be worth a look - not identified which Sony chip it uses, but it has pretty good specs
In the planetary imaging/guiding world there has been a veritable tide of interesting developments, with very high QE, high framerate and larger pixel count chips appearing in CCD and CMOS. Of these, the 70%+QE 1.3mpix Aptina MT9M034 is notable.
