I have already pre-ordered...having two of these might work out great for me. If I like the camera I can sell my HUGE Z9 camera and then use the proceeds to buy the Z8 cameras. I already have a bunch of the batteries and I can work with only one card slot. I like the thought of having two mirrorless cameras, no having to remember what I'm shooting on, and something lighter on my shoulders...I'd also love to have the 200-600 to go with it. I'll keep the 500 PF for one of them.
