I see that there is quite a lot of news on the internet about the A9ii due for release in Nov.
The previews / comments about the new camera strongly indicate that there is not a great deal of difference in the shooting capability with the weight of the changes being the ability to transfer files from camera to other devices.
There are apparently changes to the weather sealing and grip as well as mechanical shutter.
I was lucky enough to purchase my A9 for £2k with part exchange of unused Nikon lenses (A1 series) so very happy with the deal! I love the camera and as I no longer work as a professional I do not need to update it especially since firmware V 6.0 release and it more than meets all my requirements so no intention / need to update it.
Sony has come a very long way in the past couple of years and offers a viable alternative to the tried and tested top 2 DSLR top of the range models and there appears to be a slow but consistent change to Sony in the sports arena.
