Sony now making 4/3 sensors

President of Olympus, Hiroyuki Sasa, told Yahoo Japan that the sensor in EM-5 was made by Sony

The sensor in the Panasonic G3 is probably Sony too then. Sony are really cornering the market.

I doubt the G3 has a Sony sensor. I had a GH2, which is supposedly better at high sensitivity settings than the G3, and I was never thrilled with its performance in the dark. (It was merely competent in the dark, but not amazing such as an average Sony backside illuminated CMOS. The GH2 wasn't a bad camera per se, but high sensitivity wasn't its strength when compared to other recent cameras. On the other hand, the Panasonic 12MP sensor used throughout the first two generations of 4/3 bodies is pretty much horrible in low light.)

I knew the OM-D E-M5 had to be Sony from the first time I shot at ISO 5000 and got results that substantially mimicked the K-5 and D7000.

Additionally, the E-M5 has 5-Axis stabilization that is just rock solid in low light. The combination of sensor and IS allows the E-M5 to go where no 4/3 has gone before.

No, that one is by Panasonic.

Hmm, thanks for this. Looking at the previous generation quarter frame (4/3) sensors, I always felt they were too noisy for the sensor size. Given the noise performance of the new cam, looks like the same Exmor technology is present.
I'm definitely going to try an EM-5 out as a potential replacement for my waterproof K-7. The Kit lens is supposed to be pretty decent as well.

That explains a lot!

I had always wondered why they didn't just buy Sony APS sensors and make use of a crop instead of using the clearly inferior Panasonic sensors. Sure they would had to oversize the processor and memory by a small amount but it would have given the highest image quality available*.

I don't get why people give the Panasonic sensors such a hard time... No, they have not been as good as the Sony APS sensors of the same generation, but they had the same resolution (for the 16mp chips) on a platform significantly smaller - of course they weren't going to be as good!

The new Sony/Oly chip is some 18 months newer than the GH2 chip and the 16mp Sony APS chips, and the improvements I'm seeing are the improvements I would expect to occur during that time. I don't see this as some kind of magical Sony pixie dust, and I see no reason to think that the GH3 won't be as good/better.

Part of the problem is that 4/3 stills shooters such as myself sometimes greatly prefer Olympus processing/colors to Panasonic. Greatly. Because Panasonic has weird colors. And Olympus has great colors. So prior to this, the latest Olympus camera, E-P3, had a sensor that is challenged in daylight as well as dusk. No Olympus 4/3 body could provide DR in daylight or sensitivity indoors. The alternative had been the GH2 (or G3/GX1 which are slightly less sensitive). Panasonic was all lined up to screw Olympus again with the GF5 sensor. Now Olympus has better options. Maybe Panasonic could share the G3 sensor instead of the GF5 sensor now that they can't go about screwing Olympus at every step.

Anyway, here is DXO chart to show that Olympus hasn't had a new sensor in an eternity. Now they have a great sensor.

Also, you mentioned that Panasonic makes great 16MP chips. But they haven't ever sold one of these to Olympus.

I smell Monopoly on sensor making. I hope Canon keeps going at it and at least make an attempt to keep up. I would hate to see Sony just take everything by storm.
