Pascal Gauthier CEO and Chairman of Ledger announced at ledgerop3n that Ledger will release NEW Ledger Nano S device that will support more coins, more apps, and bigger screen.
That means that current Nano S device is not going to be manufactured anymore and soon it will not be supported with updates, exactly the same thing happened with Ledger HW.1, Ledger Nano, Ledger Unplugged and Ledger Blue devices.
It is possible that the production will stop at one point in the future. The new Nano S Plus seems like a bigger competitor to the Nano X than to the old Nano S though. Bigger screen, better secure element, more internal memory, but no crap like Bluetooth or faulty internal battery. Maybe they are giving up on both the Nano S and X.
