According Timelapse Cinematographer Drew Geraci on Facebook, the new announced a7R III (Amazon/B&H/Adorama/Focus Camera) has no star eater issue. He posted on Facebook said that:
Very Excited to share this side by side comparison of the A7RIII (full production model) shooting Astrophotography at 3.2″ and 10″ at ISO 12,800 utilizing the Sony 16-35mm GM lens. As you can see in the side by side comparison, with ALL noise reduction turned off in the main menu, you can easily see that all stars are present and accounted for when blown up at 100% resolution. The star-eater is no more.
