It's not really a revolutionary prediction you are making there. A new product is getting developed that is meant to eliminate the shortcomings of its forerunner. Once released, it makes the old device less attractive and outdated. Isn't that the way that technology works outside the scope of hardware wallets as well?

I am just saying that it's going to take time. The production of the old Nano S could stop in a month, but you are still going to be able to use your device and they will surely keep making software upgrades for it as well for some time until their clients either purchase a newer Ledger brand or switch to a different company all together.
