I have been happily mono-ing it for almost 5 years now but there are times where a OSC could come in handy. I am interested in an APS-C or 4/3 size with a high QE and pixels size between 4 and 6 microns. The 294 looked promising but folks have struggled with calibration. So does anyone know what new cameras might be coming soon?
Any new CMOS OSC cameras comming out soon?

Not sure about "coming out soon" , but the ASI071C is very nice if you have the cash..

Atik had a teaser message on its website just before the end of the year suggesting "new developments in CMOS coming soon", but they currently offer only the Atik Horizon in CMOS format.
But what I didn't realise before I bought mine is that whilst the Horizon has a full well of 20,000e which would routinely produce an ADU of 4096 at ADC, it then has a 16x amplifier boosting ADU to 65,536. I am told this mirrors the potential range of the best CCDs. However, it also offers variable Gain. So at unity gain (x5 Medium) you hit optimum ADU at a very modest electron count. There is an excellent video on the Atik website that explains. I wonder if similar amplification exists in competitor CMOS, and might this be where future CMOS is heading? I think it's a great camera, and its evidently at the cutting edge of CMOS sensitivity and low read noise.

Thanks for the responses. I am pretty much aware of what is available today. The 071 is an option but I was hoping one of those back illuminated chips with a higher QE would be in the works. Sony has an IMX571 that looks interesting. I am in no hurry to buy so I figured if something was going to be coming out in the next year or so I could wait.

All cmos offer variable gain. And what is the optimal ADU and how is it calculated. Some CMOS and CCDs come with 18 bit ADCs to properly sample the dynamic range

QHY's and ZWO's own websites have forums where one gentlemen in particular likes to ask if certain new sensors will be made into cameras. They sometimes reply with what they are working on.
