Sony has announced the HXR-NX3 ($3,495, expected in January). This isn't a large sensor, inter-changeable camera, and it doesn't have 4K, so it won't get a lot of coverage, but it's a good general purpose professional level camcorder.
I'm not sure if it replaces the HXR-NX5 ($3,795).
Here's a couple of videos:

The camera records to AVCHD 2.0 at up to 1080/50p (in Europe) and uncompressed 8 bit 4:2:2 is available through the HDMI output for connection to an external recorder. (It's interesting that manufacturers are now including this information - a recognition, surely, that some users like the option to record the uncompressed output externally).
HD Warrior: The NEW Sony HXR-NX3
The HXR-NX3 combines leading lens, sensor and LSI technology to achieve impressive image quality. Sony’s Exmor™ 3CMOS Sensor system with three 1/2.8” sensors provides 1920×1080 Full HD effective pixel count. As a result red, blue and green light are independently and accurately captured by separate image sensors, contributing to high resolution, high sensitivity and wide dynamic range that creates extraordinary natural colour reproduction.

"What I was expecting ( and been waiting for ) to replace the NX5U with AVCHD 2.0 using the sensors from the PMW150/160. They have just been a little slow since the introduction of the PMW 150/160 likely too many NX5U's in the channels !!! The combination of my NX5U and now FDR-AX1 will do me unless a large sensor 4K comes out with better low light than the FDR-AX1."
