This is the official press text:

Readers sent me multiple confirmations of the A7sIII preorder shipment start in the USA at Adorama. BHphoto. Amazon. FocusCamera.
UPDATE: The free $200 gift card deal on FocusCamera has now been removed

So folks, at first I called this rumor bullshit because I didn’t trust the source of the info and odd timing (right after A7sIII launch). But now reliable sources who also gave me the correct A7sIII rumors confirmed this camera is real (although with some changes on the other rumor…like price info and additional Megapixel info). So here is what they told to me:
Apparently Sony wants to show they can outperform the EOS-R5. And they do not consider it a threat to A7sIII sales because of the way more expensive price. This camera is also meant for the use at the Olympics (so I have been told) which seems to suggest that this might be more of a A9II successor on steroids.
The sources will try to give me some more hints the coming weeks…stay tuned on Twitter, Facebook, Instagram and chat with me live on Discord to not miss any rumors!
