My car has a guarantee of minimum 70% battery (SOH) after 8 years or 160000km. That's roughly 280 km range, so should be useful for many years after that.
That said, it's certainly a transition period, and it'll take a decade or two before things settle I think. It's like buying computers back in the 90's and 00's, the next processor was just that much better so it never felt like a good time to buy.
