Will you upgrade from GX7 to a GX8?

I probably will upgrade. As I said elsewhere ...

The GX8 looks like a nice upgrade for the most part to the GX7. Here's the sum from my own POV:

* Dual IS: Awesome. I predicted this feature a few years ago, and I've been looking forward to it showing up.

* Dust and splash-proof: Solid addition.

* New sensor: TBD. I'll take improved DR and SNR any day of the week. Additional resolution is minor but will be nice for some types of photography.

* GX8 size and weight increase. This mostly a down-side. Improved grip for large hands will be an up-side for some people.

* No IS on video. This would have been a significant upgrade, and since the reason given for its omission on the GX7 was "heat dissipation challenge due to small size", the additional size on the GX8 could have theoretically enabled this feature.

* No flash. This is a down-side. I've personally only used the built-in flash on my GX7 a few times in the years that I've had the camera, but a built-in flash is handy for fill use (what I mostly used it for) and trigger use.

* Shutter shock: TBD.

* EVF: Awesome upgrade. I was happy with the old one, so I'm expecting to be even happier with the new one.

* Screen: Nice upgrade on the screen itself. The articulating nature is a significant up-side for me, but some do prefer the old tilting approach (which also adds less to the bulk of the camera).

* DFD: TBD for me, but it sounds like a nice up-side. I never had issues with the focus on the GX7 (except for user error!)

* WiFi & NFC: Sounds promising. I never used WiFi on the GX7, but if it were easy to use and did cool stuff, I'd definitely try it again and see if I could incorporate it into workflow. For example, instead of the USB connection to LR, could it be WiFi?

* Video: Solid upgrade all around (obviously!)

It's not everything that I had hoped for, and I'm not absolutely certain that it will fit my usage as well as the GX7 did, but it seems like a solid upgrade in general.
