I owned a Z50 with both kit lenses and loved it's small size and light weight.

What I would love to see in a future Nikon DX body is to continue the small size of the current Z DX bodies and simply add a second memory card slot.  This could be a micro-SD slot like in my new Zf.  This would result in a perfect overseas travel body for those of us that want a backup card and do not want to travel with other backup devices (keeping size and weight to a minimum for active travel).

I'd buy two!
