Nikkor Z Lens Lineup

I am struggling to decide between 14-24mm f/2.8 and 20mm f/1.8.

I love shooting my landscape with a 14mm lens. After trying out the 14-24mm f/2.8, I absolutely love it. But I don't mind using a 20mm prime instead.

Obviously there is a huge price gap between those two. I would definitely go for the 14-24mm zoom if it had VR/image stabilisation but it doesn't.

Do Nikon tend to update their existing lenses over time?
