The a9 is currently the "ultimate" camera in the world now sans resolution. Exciting times.......I like it already. Not the price tag.
 
With that kind of spec, photojournalists may be turning heads. Let's hope SONY didn't forget their extreme weather sealing and military spec. titanium body as they'll probably see lots of real world snapshots at places with lots of human conflict.
 
Failing that, it'll be the ultimate F1 race track body to go for.....if you can also afford the "up coming" G Master 800mm lenses.  
 
However, the real difference it will make is when they trickle down their stacked CMOS / on chip processing, 20fps technology to their more affordable cameras...a7iii?  

20fps burst with AF checked 60 times per second without any viewfinder blackout is way better than X-T2
 
It has way more phase detect AF points, spread over much more of the image.
 
It has way better battery life despite having way more horsepower under the hood
 
The electronic shutter has no rolling shutter issues
 
It has in-camera 5-axis IS
 
It's full frame
 
Just because another camera comes out that's better than yours doesn't mean your camera gets worse. You can be excited for Sony and for people who will buy, use, and love the camera, all without having to hate your gear, or feel bad about yourself. The a9 is objectively better than the X-T2 in basically every objective way, and yet the X-T2 will probably do just fine taking nearly any photo you could want to take. It's okay. Take deep breaths.
