I don’t know how reliable that info is. But apprently the unofficial chatter at the Kando 2.0 event in California says that Sony had a huge and unexpected demand for the new Sony A7III. This forced Sony to delay the A7sIII launch.
What’s certain is that at the moment the A7III is still not in Stock in any US store.
