Depends on the product. Purism doesn't only sell existing (such as servers) or modified (such as minis) hw designs, but also completely original ones (such as phones).
As I mentioned elsewhere in this thread already, while the Librem 5 is becoming dated, there's still no upgrade path on the market. You need to switch to a completely different category of devices in order to get something more performant than that. I hope that'll change soon, regardless of whether it will be Purism coming up with L5v2 or someone else with their own thing.
