QHY has confirmed they're releasing a full frame mono cmos camera. It's called the QHY600 and uses an IMX455 sensor. They will be displaying it at NEAF. It seems to use the same architecture as the IMX411 and IMX461 sensors (which QHY is also showing at NEAF). 3.76um pixel size, 61mp, 42mm diagonal. It has a rolling shutter (preferable). I have a feeling things didn't work out with the IMX342 and GMAX0806 because they use global shutters.
Here's the sony sensor "Roadmap" for those interested:
