I'm not fond of the bulk, but I do think the G9 has the best handling and controls ergonomics of any camera I've used.
The G9 was $1700 on release, and is now down to $1000. In that sense, it's discounted already, and perhaps that's why you're not seeing further discounts. I've heard many people describe the G9, at its current price point, as one of the best value for dollar options right now, and I'm inclined to agree. I already have one. Getting another is probably redundant. If I ever end up doing a paid shoot - unlikely - where I need a second body, I'd probably rent a GH6.
I'd really like a G9 Mk II, or whatever they want to call it, with the new sensor. I suspect that's not coming anytime soon, unfortunately, to avoid devaluing the perception of the GH6. Not to mention, inflation adjusted, it's probably going to launch at $2000, or even $2200.
I'm also considering getting a smaller and less intimidating second body for street purposes. Not a GX9. I already have one of those, and the ergonomics are a bit finicky, and there's a slight shutter release press to shutter actuation delay. If the E-M5 Mk III had a joystick, that would have been great. I never liked the 4-way pad for adjusting focus point.
