Estimation about Samsung 16-50mm f2-2.8 price

this zoom will do to down the sales of 16mm, 20mm, 30mm, 45mm even the 60mm prime lens

You are mistaken. An 85g lens that is 2,5cm thick is a completely different thing compared to a large zoom lens. Then pancakes are small, light, cheap and inconspicuous. You can do street shooting and no one will pay much attention. You can carry the camera+pancake in your hand all day and not be worn down. You can fit pancake lenses into your pockets without trouble. The 30mm and 45mm are much faster and sharper than the zoom will be. The 45 will give much better backround separation vs the zoom and bokéh will be much better. Etc, etc.

so I think the price will be really high

Then people will not buy the lens. Even I won't buy the lens, if it's priced high. Samsung is not in a position to overprice it's lenses. They are almost unheard of on the mirrorless market. People will not buy an unknown brand's overpriced lenses. You can get the excellent f/2.8 zooms for APS-C and full frame cameras of other brands for around 750-850 clams. If you think Samsung can demand much more for the lens, you are severely mistaken. They need market recognition and more sales for the system to grow. If the lenses don't sell, the NX system will perish. And if the lens significantly more expensive than the competion, the it will be left collecting dust, while the customer choosest the lens of the familiar brand. The f/2 on the wide end of the focal length range won't help at all.
