I got this from a new source:
Every time a camera with a new sensor comes out, we (Sony) prioritize new production lots with new process routes into the system. This is happening more recently with new stacked sensor. I don’t know the details, but what I can say for sure is that we are prioritizing the new full-frame stacked sensor. The way the route is seen is quite different from other stacked sensors, so it can be said that it uses new technology. This sort of thing usually happens in our fab about three months before a new camera launches. So I guess we can expect a new full frame stack camera coming soon (maybe a9iii?) Hope this information is useful!
And this is from a second new source:
Had a chat with a sony rep at a university event who seemed to suggest that a new a9III wouldn’t have the articulating screen that a7rV has as stills photographer seemed to prefer the older style. With this in mind, he seemed to suggest that proRes for video won’t be included. He framed it like there was gonna be a move with the a9 and a1 series to purely pro stills cameras dropping decent support for video.
My thoughts on these two rumors in my latest video (don’t forget to subscribe my youtube channel):
