7.62X39 disappearing forever in the U.S ?

I being noticing that there are less options available in the U.S specifically Online there are only few manufactures making them and it’s barely available . Do you think 7.62x39 availability and price is gonna be the same before 2020 ? Do you think buying a gun 7.62x39 worth it in 2025 ? I know it’s a great cartridge but it’s not what use to be by the looks of it .

There are steel case ammo but I don’t like it I know it’s cheap but it’s preference .
