The A9 rumble is still ongoing on the web. But it seems like Sony is not done yet and we are receiving hints about another announcement coming soon. Probably within the next 4-6 weeks Sony will announce some new E-mount lenses and probably one new camera too. We got no solid info about possible specs but so more in general some of this stuff might be announced soon:
16-35mm f/2.8 GM (very likely)
new RX camera
new 135mm FE lens
What’s definitely NOT coming yet is a new A9r or a new A7III.
