Sony has announced two live stream events:
1) At the IFA in Berlin they will announce new consumer products (no new E-mount gear expected). I will post the livestream video on Sept 5 on SAR (you can already see it at the bottom of this pots)
2) At the IBC show on September 13 there will be another livestream event. The Sony A7sII was announced at the 2015 IBC show. So “THEORETOCALLY” this could be a candidate for a possible A7sII successor announcement. But I have heard no rumor that would indicate this is the case. It’s a lot more likely Sony will announce new camcorders and maybe the FX9 FF E-mount camcorder too.
Still, fact is that I heard a new Full Frame E-mount camera will be announced soon. But it might be that there will be a special third livestream event especially for this one!
