Sony UK just confirmed they will livestream the 31 August IFA press event at 1pm Berlin time. So far we do not expect any new E-mount camera to be announced on that day. The next camera to be announced in September-October will be a new RX compact.
But there may be some FS5 camcorder related news. Dennis just tweeted this:
Big news around the FS5 this week… stay tuned #sonyfs5 #fs5 #4K
