Sony A7S IV rumors: FX5 sensor?

There are rumors that Sony A7S IV will be released next October. The story is that in China, Sony registered a new device with the code name WW261362 (according to E8M). This model will support Wifi 6 and was submitted by Sony Japan. Rumored information includes:

When I saw these rumors, I feel like the A7S IV can take pictures like the FX5...?!? Previously, the A7S III was popular because it was a good full-frame video camera, low-resolution sensor, good ISO noise handling ability, and very good low-light shooting. By the way, the Sony A7S III has a huge ISO range of 40-409,600. There are many ISO test videos at several hundred thousand, you can go to YouTube to find more. However, many other information streams suggest that it could be other names such as the next Sony A9 III, or the next A7C II, the next A7c R or even worse, the next A1 II. In short, in the past, Sony clearly positioned the R series as a full frame for high-end photography with very high resolution, a line usually for ordinary people to balance shooting. As for the S series, it is full frame and has excellent video recording capabilities, so it is extremely popular among popular service crews that I know. Later, Cinema Line lines were popularized at very cheap prices such as FX3 and FX30, so people gradually forgot about the A7S series... Are you guys still interested in this line?
