Should be here in a couple days, so will report back on my findings. Interesting that Nikon decided to forego an infrared sensor on the Z7, as apparently the simple nikon infrared remote does not work. Personally would have been fine with infrared, but I suppose an RF trigger is even better. Cool thing is if I wanted to, I can trigger multiple cameras with the Vello. I can do this now with pocket wizards, but you can get one of these vellos for about a quarter of the price of a PW
Nikon's replaced the IR remote with the ML-L7 BT remote, which lets them drop extra hardware (as the BT hardware is already present)
That is extremely useful information! I'm glad I bought the vello one on amazon, as I can return it if there's issues with it.
